A selection of iChat Bugs
Ahoy!
I've been having a selection of small problems with iChat 4.0 lately, none of which are too problematic but they are all rather annoying nonetheless. If anyone has any ideas, then great!
First and most annoying: this has only began in the past couple of weeks, but when videochatting, the picture and sound cuts out for a few seconds at random intervals. The connection doesn't die, the window doesn't close etc. but it just freezes. and it does it a lot! If I keep an eye on connection doctor the bit rate doesn't drop or anything, just the video and audio quality bars drop down to zero for the couple of seconds the picture is frozen. As I said, it happens at random intervals, sometimes it's the person i'm chatting to that freezes, sometimes it's me that freezes for them, sometimes it's both at the same time! It was working fine for me prior to a couple of weeks ago. Nothing is Beachballing when it happens.
Secondly: I can't screen share (or video chat) with one specific person, only when using my Mac Pro. it's a strange phenomena because it worked the first time we tried it, it still works with other people, it works from my old PowerBook on the same internet connection (except the Mac Pro is connected to my router via ethernet) and they can successfully screen share with other people too (including my PowerBook!). Any ideas why iChat is singling this one person out?
Lastly, this is completely trivial but iChat theater has also started behaving erratically since the first problem problem arose too- when I share an image or movie via iChat theater, it usually displays both the picture I am sending and the person I am chatting with in the theater style (and for the other end they get the picture I am showing and still get a stream of me), but instead of it doing that now it just decides to put whatever I'm showing into my video box so they cant see me. It behaved normally again yesterday but continued to misbehave again today.
Details: I am using a four-week-old Mac Pro, connected to the router via ethernet, running Mac OS X 10.5.1. The Mac Pro's IP is set to be a DMZ on the router. My internet connection is my weak point as it is only 1 megabit down and a meagre 256k up, but that hasn't been a problem up until about two weeks ago. I am in London.
The person I talk to most on video chat (who I experience the freezing problem with the most) is using a MacBook Pro running 10.5.1 on an unspecified New York cable connection- we don't know how fast it is but we do know it's a lottt faster than mine.
The person I have the screen sharing problem with is using a PowerMac G4 MDD running 10.5.1 on a respectable internet connection that I believe to be 2 megabits up and down. They are in the Midlands of England.
I have also experienced the video freezing problem with someone on a iMac G5 running 10.3.9 (i think that was the last panther release at least!) with a similar internet connection to mine. They are a few miles from me in London.
I have tried fiddling with the settings that made video chatting more reliable for me on tiger (changing the bandwidth limit in iChat Preferences, changing the connection speed in System Prefs > Quicktime > Sharing) and have since put it back to what was working for me before these issues arose (No limit in iChat, setting QT streaming to 1 megabit as that's what I have going down) and none of it has really made a difference to how it behaves.
I haven't knowingly installed anything new when these problems surfaced, though I did install some more RAM about a week after the problems began.
So there's a challenge for whoever wants something to puzzle over! If anyone can work out why I'm facing such mysterious behaviour, then points are on offer. Or something.
Thanks!
-Ricky
It's time for a bump. My problems haven't subsided since upgrading to 10.5.2.
The freezing problem still exists and I have realised it is with anyone I talk to, so I'm putting this one down to my pony internet connection (though it didn't do it on tiger!). Defcom: thanks for the offer of trying to solve this through a videochat but I shall politely decline- I have a hard enough time talking to people I don't know on the phone, let alone on video chats. :[
The iChat theater problem is the least annoying of them all and I simply don't care about that one any more.
The problem with my computer singling out this one particular person is bugging me like crazy now though- it's not just screen sharing with him, I can't do anything beside text chat (or sometimes direct instant messaging if my computer is feeling like playing nice). I can't do screen sharing either way, no videochat, be it one way or two way with this one particular person on this one machine, though I can on my other machine on the same internet connection. I have been through and meticulously checked for settings that might be different between my PowerBook and this Mac Pro and nothing is different in any of the networking/sharing/QuickTime system preferences or iChat preferences.
Is it worth me filing it as a bug report through feedback with Apple, as it's such a specialised problem (only one person on one computer)?

Photoshop CS3 Selecting top layer bug
Hi,
I think I've just found a bug in Photoshop CS3 for Mac.
When trying to select the first layer in the layers palette the selection hangs for several seconds before becoming responsive. This only happens when selecting the first layer in the layers pallette.
I'm using a MBP i5 running Snow Leopard.
I was able to reproduce this anomaly on a college's machine who is also on a MBP, running Snow Leopard but has a Core 2 Duo chip.
BrianSorry, I was wrong about 10.0.2.
Of couse Adobe should fix a bug such as this, especially since it's so prominent and clearly an update created the issue.
So far you assume that the update is the culprit.
I can’t reproduce the problem with Photoshop 10.0.1 on OSX 10.6.4 so it may yet be specific to the stations you have tried it on.
Adobe will hardly spend resources on an obsolete piece of software – so you should either go through the usual trouble-shooting-routines (including System maintenance and fonts validation) to see if you can amend the issue yourself or get used to it – or hope someone else can help you in some way.
But if you expect an upgrade for CS3 you will probably get disappointed. -
Desktop selections rearranges itself - bug
An extremely frustrating bug in finder is making me lose my mind. The problem is this:
I'll select some number of items on my desktop. When I move these items elsewhere (say, another folder) the majority of the icons on my desktop COMPLETELY rearrange themselves. The icons that have moved themselves are now selected.
Not all the icons move, just most of them, and I can't seem to find a pattern to establish what prevents those specific icons from moving.
This bug is infuriating. I spend a lot of time arrange the icons on my desktop just so, only to have my desktop arrangement put in a blender everytime I move icons. Anyone have any solutions?
Edit: This problem was happening in 10.4.9, and now also in 10.4.10The problem also occurs when deleting a selection from the desktop. I haven't found any other resources on this issue and it's quite frustrating.
Surely someone has encountered this before? -

Resetting the default shape fill to follow the selected forgeround colour - Bug?
Hi guys,
Clean install CS6 - When i choose a shape layer and draw a shape it fills to the colour of my selected foreground colour. This is the way i mostly work.
However i have found if you set the colour fill for the shape layer in the top horizontal context menu, it then will not allow me to revert to my original method of working. I simply cant find a way to use the current foreground colour as a default fill for shapes anymore.
can anyone help me?
cheers
chrisnope.
Basically, the default functionality is FG for shape fill. So say, if i toggle using x it will alteratively create black and white shapes.
If, however i set the colour here (at any time).......
......... it loses that initial functionality and i simply cannot get back to the original behaviour.
I have tried this on 3 colleages machines.
cheers -
Multiple Selection Keywording/Labeling (Bug?)
I recently noticed an inconsistency in behavior when selecting multiple images and applying a color label or keyword.
If I am in grid view in the main window and use the lower row of images to make a sequential selection of, for example,
10 images by selecting the first and shift-clicking the 10th. If I apply a keyword to these images, it works just fine.
However, if I am in single image view rather than grid view and make the same selection using the scrolling lower
row, only the first image is keyworded or color labeled.
I personally like to look at a single image in the main viewer and use the lower scroller to go from image to image and apply keywords. If I need to apply to more than one, I shift click and select multiples.
However, I am not able to do this when viewing only a single image in the main viewer.
Am I missing something in the logic of this behavior that perhaps is useful?
Can someone attempt to reproduce this?
Thanks so much for your help.

...what is the point of being able to multiselect in the film strip when in single image view? It seems to me that a multiple selection in the film strip should behave the same no matter which way I view the main window. If it does not, there should be some logic to this behavior, not simply, "That's how it works".
-Scott
Here's some practical uses for being able to select multiple images in the filmstrip:
1. You're using loupe view and want to limit the number of selections so you are able to browse and choose the best image from a specific group of similar images.
2. Same as 1 but you want to apply ratings or labels to the images in the group. The rating/label will be applied to only the most selected image, not all of them, which is the desired behavior.
3. When in survey view the selection is controlled by the filmstrip. You can add and remove images from survey view by simply clicking on them in the filmstrip.
4. When in compare view, you can change the select/candidate images by clicking in the filmstrip.
There might be more, but I use these all the time. -

Empty Select display element bug?
Hi,
I have added some code to a userform that uses a Select element in the form, i.e. the user is supposed to select from a list of options
My problem is that the generated html doesn't include the options in the final output.
saving the form will however set the variable to whatever default I set it to.
Now, this worked fine on our test system, but not on our acc and prod.
The allowedValues and valueMap are calculated (i.e. selected from an internal structure) and are set to the right lists and maps before it goes into the final html render phase :P
If I enable block tracing, I can see that the references are filled with data before the final render...
Anyone seen this behaviour before?

So, I found out this much...
in my "newer" system, same WAS and same IdM deploy, if I have valueMap set to null, it will use that to map with, making it a nulled map :P
in my "old" test/development server, this worked fine
in my newer acc and prod it did not :P
easy to work around ofc, but more xpress code to do it... -
Hi I'm trying to receive a share screen with messages, my computer is an imac 2008, with Mountain Lion 10.8. The other one is an imac too, with 10.7.X and ichat.
This error only happen with my computer.
If I share my screen my screen it doesn't happen.Hi Mark,
It seems you are the Original Poster have different problems.
I have three computers here
1) an iMac running Mountain Lion and Messages ver 7
2) A MacBook Pro running Snow Leopard and iChat 5
3) A G4/1ghz Dual Processor tower running Leopard and iChat 4
I and Screen Share, Video chat and Audio chat between all of them.
I tired Bonjour and AIM names to do this.
It did take several attempts before the iMac seemed to "remember" it had done this in Lion and iChat 6 and Messages beta.
On all computers in iChat or Messages Menu > Preferences > Video Section I Have the Bandwidth set to 500kbps.
This helps, if like me, you have someone using a X Box 360 On-line and using varying amounts of bandwidth or your ISP service speeds vary or one of you is much faster over the internet than the other.
With the Video chats and the "Buddy List" I would go one stage further if you have several account logged in.
Go to the Messages Menu > Preference > General Section and untick the option that links the Accounts Into One Buddy list.
This may take up more desktop screen area but you can be sure of using the "right" name if the person has more that one ID or Screen Name in their Address book card.
It also makes it easier to check the Security Setting in any AIM Account that might be Blocking Buddies.
Get your Parent to start the chat.
Apple may have reduced the Testing Accounts to one at present but can you Video with any of table 1 ?
http://www.ralphjohns.co.uk/ContactTesters.html
iChat 6 and Messages log in to AIM on the API servers using port 443
This tends to mean you can login as this port is below the 1024 threshold
If you set up Port Forwarding before with iChat and you have a different IP now (sometimes happens when Upgrading) your Router settings may not be pointing to your computer.
I would use UPnP (or Port Mapping Protocol in a Base Station) if you have it.

IPad's desktop-like select+double-click bug
Suddenly my iPad is not responding as before. It is acting like a regular desktop window manager!
Now, when I touch an app icon, the icon is selected. A thin line appear around the icon, like it would be on a normal desktop window manager. Then to launch the app I have to double click. The strange thing is that even if I double click somewhere else, it's the selected app that is launched.
It's exactly the same for the virtual keyboard. One click select the key, two clicks (anywhere) press the key.
If I swipe one finger left, the icon to the left is selected (and vis-versa).
What the ****? Is this a secret features I have somehow activated?
Is there any simple way to go back to the good-ol' multitouch interface?
I have tried to shut down and reboot the ipad (home-click+power 5sec). Nothing works.
Any ideas?
Cheers
PireYou must have turned on voiceover. Either triple click the home button and see if that fixes it OR go to Settings -> General -> Accessibility -> VoiceOver and turn it off.

"The application iChat quit unexpectedly"; "Library not loaded"?
Whenever I try to launch iChat, I receive "the application iChat quit unexpectedly" error.
Neither "Relaunch" nor "Reset and Relaunch" fix the issue, and when I click "Report" and view the "Report Details" it gives the output enclosed below.
The gist of the error is "Library not loaded: /System/Library/PrivateFrameworks/ScreenSharing.framework/Versions/A/ScreenShar ing".
It also says "Reason: no suitable image found", but it also says it:
"Did find:
/System/Library/PrivateFrameworks/ScreenSharing.framework/Versions/A/ScreenShari ng: unknown file type, first eight bytes: 0x6E 0x61 0x6D 0x65 0x20 0x20 0x48 0x42"
I've removed and reinstalled iChat (when in Safe Boot -- with the Shift key) from Disk 1 of the Mac OS X Install disk 1 by using the "Optional Installs.mpkg" installer and selecting only iChat, but I still receive the same error.
How can I reinstall this "ScreenSharing" library? Would that likely fix the issue?
PS - I just realized that if I go to "System Preferences" and click "Sharing", the options are totally blank! I can't see any options or change any Sharing configuration! All my other System Preferences show up correctly.
So now the question becomes, how do I install just the "Sharing" System Preference?
Or should I try to reset permissions on the Sharing System Preference somehow?
Thanks!!

Note that the first eight bytes of a Universal-Binary Mach-O image should be 0xCAFEBABE, 0x00000002. Since the existing file was so vastly different, after all else is said and done, you may want to make sure your hard drive checks out okay in Disk Utility. -
I don't get it: Address Book's low quality, UI mess, and bugs stand out...
... especially compared to all other great Leopard apps.
Hi Folks. I'm a switcher from Windows XP, and generally I've been very impressed with 10.5.2, and happy with my decision (Macbook Pro 2GB, 2.2GHz). However, one of the most incredibly painful experiences I've had is using the Address Book application.
Please forgive my sounding negative, but compared to the other apps on OS X, it is really, really crappy. This is after having imported and edited around 1,000 contacts. The ultimate deal-breaker here is trust: I put many hours into this thing, to find it's extremely easy to lose entries/data. The undo, UI mess, and save problems combine to make me nervous as **** every time I edit. Hit escape? Where'd that phone number go? Hit undo? You might have undone something three edits ago!
I don't want to be unfair to Apple - OS X is really good, and I recommend it. But this one program just is not ready for prime time... Three things:
First, can anyone give some background on this program? Not to be rude here, it just feels like something that was thrown together without much thought, was a very low priority, or was a summer assignment to an intern as a "learn the API" demo, but who didn't have the experience to put together a solid, functional program.
Second, can anyone recommend a usable replacement that works well? I have Office 2008, with Entourage, but I frankly don't trust MS apps to work well either, or to play nice with others (e.g., Spotlight).
Finally, below are a few observations after using the program for a week - not complete bug reports (sorry, I'm too busy to debug for you, Apple) but just a few examples of the pain the program's caused me. Am I alone in this?
matt
o #1 problem: It's lost my trust - the ultimate sin of a program. If I
hadn't created a backup, more than once I would have been extremely
screwed. Cards someone disappearing, field edits lost, etc.
o Edit/view modes: Bad. Apple: go read your own UI guidelines on this.
o What's up with Save? It seems to be automatic (saves when I exit),
but also has a command. Sadly, there is a bug in which Save disabled
when in View (not Edit) mode, >> even if changes have been made <<
(e.g., in the notes field, which can be edited in non-Edit
mode. Another example: add a smart group, try to save - gets a beep.
o Selection in Notes field: I can not figure out the selection
logic. Clicking on it selects all, but seems crazy inconsistent, e.g.,
it re-selects all when trying to make an edit. Want to really see
problems? Try shift-clicking!
o Undo is horribly unpredictable - It should simply undo the last
edit, whether it was typing in a field, merging cards, deleting a
card, etc. Unfortunately, it's not consistent. For example: delete a
card, edit a few others, then undo - undoes the delete, not the
edits. Many other problems with undo...
o Escape key: I can't figure this out: Does it undo, clear, or abort
editing? It's a mess.
o Printing formats: I can't say enough how terribly limited this
is. For example, it doesn't support classic planner sizes, and the
compact format is ungodly.
o Non-mouse navigation and editing is extremely frustrating, and 100%
keyboard operation seems impossible. For example, you can't select
field pop-ups (work, mobile, etc) or check the "Company" checkbox.
o CSV import just plain broken - unusable. I read practically every
post here on the topic, and it's terrible. I was able to work-around
the bug by using vCard instead, which does work. Had to convert from
CSV to vCard using an external program (Gmail). Ugh.
o BUG: Creating a new note puts an extra space character in the field.
o No support for encrypted information in Notes field. Isn't this
built in to OS X?
o I'd really like to be able to copy an address in one card, and
paste it into a new contact with fields preserved.
o BUG: Can't print multiple smart groups: Shift-select two ore more
smart groups, type command-P, it de-selects!
o Bug: Editing fields sometimes allows selection of the field name
itself, e.g., you can select the "Note:" tag on left.
o Q: Any way to filter items that are printed by whether a field is
empty or not? I have some without phone numbers, and I don't want to
print them...
EOFAre you using the access control list on the AirPort Extreme base station (AEBS)? If so, turn it off.
Open the Network preference pane. Drag AirPort to the top of the list. Better yet, disable Ethernet. Can it connect?
If that isn't it... the list of possibilities is short. The IP address starting with 169 indicates that it is not properly connecting with the DHCP server on the AEBS. Apparently, reading through your text, you have successfully established the wireless connection with the AEBS it is the communication with the DHCP server that is failing.
Have you been able to try the MacBook on other wireless networks?
Did you accidently configure this AEBS to use WDS? If so there is an option that prevents wireless clients from joining.
If you do have WDS enabled, you should disable it since you aren't wirelessly connecting any other base stations. -
The Origin of Random iChat video failu
I hope this topic gets a lot of response and reply from as many people as we can get involved. If you are like me you have been using iChat more of less happily for some months and then suddenly all **** breaks loose and you cannot initiate chats with one or another of your usual partners when neither of you have changed anything. PERIOD. Maybe it comes and goes, maybe you "fix" it with a seemingly random change. I would love to hear from someone and everyone about what can truly cause these problems. I have two brand new macs, an iMac about 5 months old and a 2 month powerbook. There are days that the powerbook will work on a video chat while the iMac fails every time (trust me we tried a LOT of times). In this case they are BOTH sitting behind the same cable modem,using the same wireless router and have been identically configured (trust me I checked, I looked in all the places etc etc). So, in my mind that eliminates the usual carbon copy post most people make telling everyone to check their router, firewall, NAT, uPnP, port forwarding etc etc etc.
My question to everyone is, what can POSSIBLY work in this way, ie which component is iChat having issues with.
OR
Is it more likely a network issue EXTERNAL to my house and my chat partners home, i.e. bandwidth, routers etc etc... I don't think it could be speed. During a repeated failure I and my chat partner both went to speedcheck.com and both had well in excess of 500 kbps up and down, more like 1Mbps but I cannot recall the number so I dont want to exagerate here. . I am leaning this way just a bit because it works, then stops, then works, then fails with a different individual, then all is good etc etc you get the idea.
Basically what can get you failures that act this way. I am STUMPED. Is it apple code and an iChat bug? Is it just complicated (poor excuse), or is something really broken somewhere that somehow works most of the time until it decides not to work and then suddenly heals itself (you can see why I feel this is a bunk excuse).
Anyhow... chime inYes, I think weʼre a growing lot of people who experience the severe limitations of iChat AV while other IM-clients have no problems and Skype is getting through everywhere. Textchatting is the only thing which works, but well...
Anyway, so far I have found out that one of the main reasons for these kind of problems, is that iChat is being a very "law abiding" citizen. It obeys rules and follow protocols while no one else seem to do so and that leaves a lot of us with problems.
There are ISPs who are blocking certain ports iChat needs to establish AV-chats and they do this mainly because they sell similar products like VoIP-telephony. The problem then, if you use a laptop and are travelling, it all depends on the network you connect to. Then it of course depends on the network your buddy is connected to.
To give an example; I used the landlordʼs internet the last two places I lived and I could not initiate a AV conversation nor accept one. I am still living in one of the places but decided to get my own internet and asked specifically that the ISP didnʼt block such ports as needed by iChat and I found the one for me - and it works again! But that will of course change if I take to the road with my iBook...
So, Apple, please make iChat a more forgiving and flexible application! If others can do so - MSN, Yahoo Messenger, Skype - it canʼt be that hard. And iChat is good when it works, maybe even the best. But my mother canʼt see her children and not hear them as we all intended her to do. Others cannot stay in touch with spouses and friends and colleagues when they are away.
Well, I hope my two øre can contribute to understand what the problem is. And to move Apple to do something about it. -

driver.
* Synopsis:
The parameters of prepared statement (I tested SELECT's and
UPDATE's) are bound in the reverse order.
If one do:
PreparedStatement p = connection.prepareStatement(
"SELECT field FROM table WHERE first = ? and second = ?");
and then bind parameter 1 to "a" and parameter to "b":
p.setString(1, "a");
p.setString(2, "b");
then executing p yields the same results as executing
SELECT field FROM table WHERE first = "b" and second = "a"
although it should be equivalent to
SELECT field FROM table WHERE first = "a" and second = "b"
The bug is present only in "thin" Oracle JDBC driver. Changing
driver to "oci8" solves the problem.
* Version and platform info:
I detected the bug using Oracle 8.0.5 server for Linux.
According to $ORACLE_HOME/jdbc/README.doc that is
Oracle JDBC Drivers release 8.0.5.0.0 (Production Release)
* The program below:
The program below illustrates the bug by creating dummy two
column table, inserting the row into it and then selecting
the contents using prepared statement. Those operations
are performed on both good (oci8) and bad (thin) connections,
the results can be compared.
You may need to change SID, listener port and account data
in getConnecton calls.
Sample program output:
$ javac ShowBug.java; java ShowBug
Output for both connections should be the same
--------------- thin Driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
[ The same - with buggy reversed order (should give no answers):
aaa
--------------- oci8 driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
aaa
[ The same - with buggy reversed order (should give no answers):
--------------- The end ---------------

Selecting and Dragging multiple clips - CS6 Sniper mode
With the introduction of ability to select Edit Points, now it's inconvenient to drag multiple selected clips or add clips to selection because in some cases - depending on timeline zoom state and/or clip duration. The edit points are altered instead of the clips, that behaviour drives me nuts. It leads to a necessity to do one of the following actions before selecting and/or dragging multiple clips with comfort:
sniper mode - put the cursor over a place in the selection where the cursor will not indicate Edit Point trimming mode.
to avoid loosing selection when using sniper mode - Group the clips after adding every clip to selection and/or after a dragging operation
dynamically change zoom state so that you will not have to use sniper mode
use copy/cut/paste - may involve a necessity to do additional pre-pasting steps
IMHO, this behaviour should be rethinked.
How fast it was in CS5.5 and older versions:
Please, Premiere Pro Programming Team, especially Tim Gogolin, Steve Hoeg, Peter Lee, Gerry Miller, James Mork, Vivek Neelamegam, Axel Schildan, Jerry Scoggins, Sven Skwirblies, Tod Snook, Jesse Zibble, rethink the behaviour of selecting and dragging clips. Start giving links to beta-versions to other editors too, not only to editors like Philip Bloom.
Selecting edit points is sometimes helpful and sometimes distracting.
To get the best of two worlds (CS6 edit points vs. CS5.5 and older) - a switch could be added to Keyboard Shortcuts list, like the "hidden" Add Clip Marker shortcut.
Let's name it "Application > Sequence > Select Edit Points".
When Shift- or Shift+Alt- key is pressed and some Clip is selected, clicking on an edit point of another clip should add a clip to selection in the same way as previous versions of Premiere Pro did:
To drag clips in legacy sniper-free mode only a switch can help. Let's name it "Application > Sequence > Select Edit Points when Multiple Clips are Selected".
To add comfort to the editing process - selecting/dragging multiple clips - additional switches cannot be avoided. Additionally you may add an option to the Preferences > Trim:
Allow Selection tool to choose Roll and Ripple trims without modifier key
Allow Selection tool to select Edit Points while multiple Clips are selected

Concise problem statement:Inconveniences when selecting and dragging multiple clips
Steps to reproduce bug:
1.Create a Selection of multiple clips with Shift+Click
2.Try to drag the clips
Results:With the introduction of ability to select Edit Points, in some cases (depends on timeline zoom state and/or clip duration) now it's inconvenient to select and drag multiple selected clips because the edit points are selected instead of the clips
Expected results:Clips should be selected/dragged like in CS5.5 and older
Link: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishformWith all due respect Kevin, nobody at Adobe has the right to change a program SO drastically. I am also a mouse person, and am MUCH faster using the mouse, vs the keyboard.
When people have invested YEARS into a program like Adobe, they get used to things, how things work, the feel of a program. I really don't see how you all can just change it on a whim. IF you are going to do this, BOTH methods should still work. You cannot just stop the way people are used to editing. You can't just decide to change a program so drastically, that it doesn't feel like a program we have grown to love over many long years. If Adobe on a whole is changing things, just because a few people in your company voice opinions like I've quoted below, it's not the way to go. Adobe should be really putting feelers out there, and seeing how people are really using the program. Things should be getting easier, more powerful, sure that's natural, but you can't just decide to remove things that mouse users do every day. :-(
Upgrading a program, and changing it to this degree, are two different things in my book. I have not yet upgraded, but it is very scary - the things I'm seeing. For one, way way too many bugs. The amount of bugs on so many boards being reported are just beyond comprehension.
And a final note, I for one, am very glad Steven is posting these videos ( I'd like to hear him go through steps though - just watching the video with no audio of what he is doing is not so great, however after watching some of his posts, he's knows what he's doing, and has a good head to think with )
I mostly read posts, but I thought I would voice my opinion, if none of us speak up, nothing will get changed. I'm really hoping that Adobe implements some change in the next revision .5 or whatever it will be called. Reading posts like this one are really depressing. Did you watch Steven's video on a simple task as moving multiple clips around on a timeline ? Doing this with a mouse just isn't going to work for many, removing simple tasks by way of using a mouse would stop me from upgrading.
Please address this in upcoming updates.
Dave.
