One dock icon moves and disappears

Recently my Firefox dock icon started moving all the way to the right of the dock when it was open, and disappearing from the dock when it was closed.
I have read a couple topics on the same issue, which recommended resetting MobileMe sync data and to unregister/reregister the offending computer. This did not work.
I discovered that when I move the Firefox app from my applications folder to my desktop, then place it in the dock, that icon stays put in the dock (and the desktop icon stays put on the desktop) - until I open Firefox. At that point the static Firefox dock icon 'duplicates' into a second far-right dock icon. When I click to another application then click back on either the static Firefox icon or the new one on the far right of the dock, they both work to make Firefox the front app.
I want my Firefox dock icon to work again, like in the golden days of old. Any recommendations?

I also dragged the dock two utility files (com.apple.dock.db, com.apple.dock.plist) to the desktop and relogged, resetting the dock. This did not work.
I reinstalled Firefox, but that did not work.
The Firefox dock icon stays put on the other iMac user and on my MBP.
Crazy maddening. I feel like there must be something that is corrupted, but am not sure what.

Dock icons STILL keep disappearing.

There is a thread here that says 'SOLVED' but it was not solved for many people posting on that thread. Here is the URL for it:
http://discussions.apple.com/thread.jspa?messageID=7855781&#7855781
So, I have begun this new thread with the same topic. My dock icon (mail) keeps disappearing. It slides to the right then disappears. Moving the plist dock and db to the trash then rebooting does not fix this problem for me, nor many others on the initial thread. The problem is not specific to the 'mail' icon, other icons are affected as well.
My mail icon is a big deal, please help.

I have three macs that I use every day. I am so annoyed that I can't make any changes to the Dock icons on any of them, and I am sure it has something to do with MobileMe. I have turned off syncing the Dock but it still won't let me make any changes. I have tried the methods people have mentioned in various threads but none of it works.
When I make a change to the Dock, I am doing it for a reason. For Apple to have implemented code that would under any circumstances undo the change that I have made is ridiculous. Everything else about Leopard is great, but this is really, really frustrating and messing up my work groove.

Dock icons will not disappear when I drag them to desktop or trash

On my MacBook Pro, when I drag an icon from the dock to the desktop or to trash, it bounces back to where it was on the dock. I tried to move Applescript Editor, AppleWorks 6, Keychain Access, Activity Monitor, Quick Time Player and several more icons and they all did the same. Each icon that will not disappear, has a blue dot reflection underneath it.
I moved one of the icons without a blue reflection to the desk top and it did go up in smoke, but as soon as i replaced that icon from finder back to the dock, it also had a blue reflection under it and I could not make it disappear again.
If anyone can help me, I would appreciate it. Thank you so much,
Arudi

You're only supposed to drag icons out of the Dock if you want to remove them from it; running applications won't disappear immediately but may do so when quit.
If you're trying to put icons on the desktop, find the items in the Finder and drag them there with the Option and Command keys held down.

I've been getting a lot of pop-ups only on firefox (my other browsers work fine) and recently I also had a homegroup icon appear and disappear on my desktop??

I was wondering if the two coincide, what is(are) the source(s) of this problem? how do I remove the homegroup from my computer and eliminate the unwanted pop-ups? I have windows 8 on my computer.

Hi to block pop ups completely here's how:
Disabling all popups in Firefox
Type "about:config" (without the apostrophes) in the browser's address bar and hit the enter key.
First time users need to confirm that they be careful on the next page.
Type or paste "dom.popup_allowed_events" (without the apostrophes) into the search field.
The value of the preference highlights all events that are allowed to spawn popups.
Double-click the preference and "REMOVE" some or "ALL" of the items here. You can also add some if you want to do so.
note if you are successful, the next time a pop up comes you can set to disable notification from appearing.

Disappearing Dock Icons since downloading iTunes 9

I just downloaded iTunes 9 and ever since I installed it on my macbook pro, dock icons have been disappearing. They are still there and I can click on them to launch the application, however the picture, for example the icon for iTunes is invisible.

I've got almost the same issue!
iTunes 9 itself has no Dock icon, but invisible icon still exists.
Trashed iTunes 9 and re-installed it with the .mpkg downloaded from apple.com ... funnily enough while installing, Installer.app had no icon! The iTunes icon remains invisible.
All other apps appear to be fine.

Dock Icons become QUESTION MARKS

i have DOCK ICONS that i have told to stay in the dock (this is how i start the programs) and every two weeks or so one or another one of these suddenly shows up as a BIG QUESTION MARK.
i asked this once before and someone said i should just drag the icon off and start the program again and make sure to tell it to stay in the dock.
but this is a major pain and makes it seem like there is something wrong with the OS not to mention it is really annoying to have to constantly re-organized my desktop.
does anyone know WHY this may happen and if so HOW to keep it from happening?
i mean, is there a PATH that gets linked to this icon and moving this data will somehow create the question mark? some other explanation?
TIA for any help.

hi kappy. again a BIG THANK YOU for helping me on this.
these are good points but there is definitely a different set of aspects to working on a mac with respect to the workflows regarding app install but i am not technically knowledgeable enough to tell you why this is so. i can just say that it is very confusing and it could use some cleaning up. just the fact that i have to post this question is an indication of this IMHO.
also, at the same time one simply has to look at all the Application folders on the mac and the various ways they are accessed or pointed to. when you say something like you just have to (manually) put the app file in the applications folder these things are all over the place.
i have an "Applications" folder under my Home folder that has two folders and one application that has installed themselves there. then i have a Dock icon that says Applications that has a list of programs, and then i have a desktop shortcut that has a list of items. if i ask myself the reasonable question of - well - HOW do i drag and drop the .app file into the Applications folder like i am supposed to, or WHERE is the Applications folder that shows all the items in my desktop shortcut or in the dock icon - - reasonable (and reasonably intelligent) people might be completely stumped.
now i /know/ that this "other" Applications folder is actually listed under my HARD DRIVE icon and not my home folder because if i double click on the desktop icon or if i open the dock icon in finder i can see that this is the case. however, this means that we are talking about something that is HIDDEN from the user on the mac OS. so for me to MANUALLY add a . app file to the Applications folder i somehow have to - well - presumably i have to make the leap of faith that when i add this file to my DESKTOP ICON i am adding it to the correct (hidden) folder and not to the one that i can see plain as day in my Home Folder but which appears to contain next to nothing.
I mean, i am manually adding an app to a desktop icon that has the same name as another folder so that it arrives in a hidden folder with the same name. this is ridiculous. this is just dumb and probably goes a long way toward adding to the confusion. the fact that the Home Folder level Application folder is the one that is visible is even dumber.
again, a set of prompts upon program installation might be a Mac OS level need and not something that should devolve down to the developers who probably have enough on their hands trying to keep up with changes in the from OS to OS.
as a concrete example on this thread - the answer my issue is that either there is no .app file in the /hidden/ Applications folder for the dock icon to continue to reference or that the ICON was added to the dock while the .app file was somewhere and now it is no longer seeing this .app file where it originally saw it.
A slightly off-topic BTW:
do you know why I have one app file in particular that i see in the Home Folder Level Applications folder? this is a reasonably sophisticated company ostensibly they think this is a better place for the App and /they/ did this from what i can tell instead of me accidentally screwing this up because i was sleepy or distracted and not thinking about the Escheresque aspects of installing these .app files presumably? i mean, this in itself is confusing since I DO see this app icon in the dock and I DO see this app in this folder (all by its lonesome basically) but i DON'T see this app listed in my DOCK ICON list of Apps (or in my desktop shortcut list of apps) which from my perspective would/should basically cause a normal human being to think that the app is not installed...

When I open Thunderbird no windows will open on my desktop until I click "Hide Thunderbird" then click on the dock icon again, Mac OS10.8

When I click on the dock icon to open Thunderbird, the menu at the top of the screen opens, but no windows, ie. Mail & Newsgroups, New Message, About Thunderbird, etc. will open on my desktop. I have to click on Hide Thunderbird, then click on the dock icon again, and then all of the windows I attempted to open become visible. This is on a Mac running OS 10.8.5, Thunderbird 3.0.11. All runs normally after this until I quite Thunderbird.

Hello,
Sorry you are frustrated. If you have improvements you would like to make, you can file them to the [[Suggestion Box]] and the Firefox logo in the top left with upside down arrow is the Firefox button containing menu items. Try a clean reinstall as instructed below to see if it resolved your issue.
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!

You do what it says.

The behavior of the emergent forms of the software in RD Web App is different in Mac and iPhone-iPad, they appear and disappear intermittently. (Remote Desktop Services - Azure).

In Mac the forms are not integrated as one window, they appear and disappear intermittently. There is no option to configure it. In the iPhone-iPad RDP app, there is no problem with
that, when some form gets focus the other forms remain stable. Do you have any suggestions?<o:p></o:p>

DVD project with movie and additional files on same disk?

Hi-
Dell 9200 (aka XPS 410), WinXP Pro SP2, Encore 2.0.
I have a DVD project that I am assembling and need to include different types of files on the same DVD. I have an educational movie that is already formatted on a stand-alone DVD (just like one you would rent from Blockbuster). It needs to go onto a DVD along with some additional supporting files in .pdf and .txt file formats. The DVD has to be able to autostart and play on both a home TV/DVD setup as well as a computer. Users also need to be able to access the additional .pdf and .txt files if it is viewed on a computer. Can these two viewing arrangements co-exist on one DVD? Seems to me that it would all work fine if I converted the stand-alone DVD movie into a something like a Quicktime or Windows Media file, created a XHTML file that can be used as an autostart menu, and then link the movie, .pdf and .txt files from there. All of this can then be burned onto one DVD that can be viewed on a computer, but I assume it would NOT be able to be viewed on a TV/DVD home setup. On the other hand, If I created a DVD using Encore I could just make an autostart screen with menu, but I don't think the menu would suppport something like linking to the .pdf and .txt documents (not that they could be viewed on a home TV/DVD setup anyway.
So, am I looking at having to make two separate DVDs--one with the movie and one with the additional .pdf and .txt materials? Would this have to go onto a dual-sided DVD? One side with the movie and one side with the additional materials? Would it be best to just convert the movie and stick all the files on one DVD? (Even though my boss hates this idea because it will reduce the quality of the current DVD movie).
Any suggestions would be greatly appreciated.
-=Scott

eDVD is one option. It uses the Interactual Player to link to your extra content directly from the DVD material. Your other option is just to create your own separate content for use on computers. DVD players only pay attention to the VIDEO_TS folder, which must be in the root directory. If you also have an autorun.inf in the root directory, Windows-based systems will follow the instructions there rather than treating the disc as a DVD-Video disc. So you could use an autorun.inf to launch whatever you want to play on the computer (Director projector, other executable, etc.). You can add that extra stuff to the DVD either by using the "ROM Content" feature in Encore or by building to a folder and then burning your disc with other burning software (be sure to use the UDF filesystem or it won't work in DVD players).
Notes:
1. Mac computers will still launch whatever application is set to handle DVD-Video discs in the System Preferences (usually the Apple DVD player).
2. If computer users need to view the DVD-Video content, you will need to give them some help in doing that. (i.e. instructions to manually launch their software DVD player, linking directly to the DVD-Video content from your Director project, providing a separate copy of the video, etc.)
3. eDVD's effectiveness is diminished by the fact that it requires installation of the Interactual player. If the user is unwilling/unable to install software on their computer, such as many corporate/educational users, they will be unable to take advantage of the eDVD features.

Xbox One Lego The Movie preorder minifigure

I've preorder the Xbox One Lego The Movie and picked it up on the release day. The staff told me that they didn't received the preorder figure with the game and will contact me as soon as they received it.
Since is now more then a week and no reply from the store and I would like to know is all Bestbuy don't have it or just the Emeryville store.

Hello virtualon,
Thank you for pre-ordering your copy of The Lego Movie Videogame from Best Buy! I am sorry we did not have the Lego figurine to go along with it. Regrettably this was a limited quantity item and I would not be able to verify availability in any of your local stores. If you will be visiting any of them I would certainly encourage you to as an associate if they have any available.
Thank you for being a My Best Buy member. Please let me know if you have any other questions today.
All the best,

Director app on Mac: Dock Icon Drop Down List displays with no title

Hi,
we have a Director application on mac, that changes it state from window-mode to full screen-mode. It is done using Resolution xtra
Now we've discovered following peculiarity
When program is in windowmode and user presses CMD-Button + Click Dock Icon, a dropdown list appears over the clicked dock icon. And the problem is, that besides of the name of our programm there is another item in the list, that have no title.
What can be the reason of this? Is there some workarounds for that problem?

Images I move from one folder into another are disappearing, at first it was occurring immediately if I did not copy and paste the images. Today however I found out that images I had been using for days just up and vanished from their new location.

Images I move from one folder into another are disappearing, at first it was occurring immediately and only if I did not copy and paste the images. Today however I found out that images I had been using for days just up and vanished from their new location. A few of these images had copies in another folder that remained and the ones I couldn't find may or may not have ever had copies. I had backed up my system with time machine recently as well, so I went into the backup to retreive the lost images. When I searched and found the backup copies I got the error "the file alias cannot be opened because the original cannot be located". The crazy thing is that the images that remained on my computer did not give me the same error and opened like they should.
In short images that I am creating, saving, and using are disapearing so epically that even time machine versions are affected when retrieval is attempted. Any suggestions as to what I could be doing wrong without realizing it? Or perhaps other people have had similar bugs that are software related and have a solution?

Hi Kevin,
I understand what you tried to do but it doesn't work that way. Swapping drive names will just mess things up.
You should be able to reconnect the files though: in the Locate Referenced Files dialog make sure you click the Show Reconnect Options button — this will give you access to all the connected drives. Locate one of the files and hit Reconnect All. Should do the trick.
Best

HT2474 Dock icons disappear

How do I keep the dock icons on the screen while on a webpage. I disappears and takes a little effort to get it come back up again. How can keep it there all the time? Tried using the system preferences but it doesn't have that option. The dock preferences also has no function to do this. In my older Imac, the dock icons are alway at the bottom, don't have to make them appear. Thanks.

This is happening for me too. Restarting does fix it, but it tends to come back after a day or two. It usually starts off with just one icon, but eventually it strikes most of them. Only one of the two shadows remain - the one that goes up against the desktop. The one that appears against the dock is clipped away, you can usually see the top four or five pixels of it if the entire icon disappears, but it's mostly gone. Some apps only lose part of their icon - for example, some icons tend to show a small sliver about halfway down. I'm guessing this is probably some weird clipping bug, or maybe it's just the bitmap cache getting partially erased.
Also, as long as I'm talking about the dock, why do both shadows bounce with the icons? Shouldn't the shadow that rests on the dock logically stay there?

Help - Disappearing dock icon

Here is a strange one. A friend of mine has a MacBook w/Leopard and his iCal icon disappears from the doc when he closes the program. The date remains. The rest on the icon is gone. What can we do to fix this?

I've tried everyones suggestions with no solution... I did copy my iCal app from my other Mac running Leopard to my MacBook Pro and the deleted the caches/plist/etc. This fixed the calendar appts not showing up without navigating and the buttoms are now drawn in iCal and preferences (They werent prior).
Just need my Dock Icon fixed - drives me nuts!!
