Lion: Trackpad-Gestures disabled while Drag&Drop

Dear Community
Since I have Lion on my MBA (late 2010), some gestures don't work anymore...
e.g. when i want to move a file into a folder: on Snow Leopard, i dragged the file with the left hand on my trackpad, then i used two fingers of my right hand to scroll down and i dropped the file into the folder i wanted to move the file.. Worked like a charm...
Now on Lion: when i'm dragging a file or something, all other gestures are disabled!! :-( is this a setting? Or am I the only one with this problem?
Greetings from Switzerland

same problem here:

Trackpad "buttons" disabled while holding down key on keyboard

Hello,
ben having the following issue with the trackpad on this laptop:
when playing games and holding down the W-key for example, the click functionality on the trackpad seems to be disabled. Neither tapping the trackpad nor clicking the lower left side works, untill i release the said keyboard key.
the most usual issue, the entire trackpad beign disabled while typing is already "fixed" by turning the palm check off entirely. But dont seem to find option that enables the mouse button presses.

When using Lion trackpad gestures.

When using Lion with the trackpad gestures is there anyway to keep the 2nd display (extedned display) from moving?

What do you mean 'moving'?
If you mean, can you change desktop in the main display but not the second display, I'm afraid the answer is no. They are logically tied to the same desktop space.

Mountain Lion trackpad help

Is there any Mountain Lion trackpad gesture that brings all open applications up to the front for easy quitting? On Snow Leopard I was able to swipe 4 fingers to the right or left and quit my applications easily by hitting "Command" Q. I know how to quit applications by right clicking on the application while on the dock, but is there an easy way to bring all open applications to the front?

Press command-tab, and continue holding down the command key. You can cycle through the list that appears (all while keeping the command key held down) by pressing the tab key, or shift-tab to go backwards. When a particular app is selected, press the Q key (remember, you're still holding down the command key!), and the app should quit. Repeat until you have quit all the apps you want to quit.

E-mail address "overlay" with "drag & drop"

The following errors occurs doing a "drag & drop" from the Address Book or using the "Contacts Sidebar". Unless you "drop" at the end of the line, sometimes it "drops" exactly where the cursor was (because sometimes I see a red cursor and sometimes I don't so have no idea of exactly where it will place it) "overlaying" the e-mail addresses on the line (but sometimes, it put each one of the e-mail addresses on a new line). Either append them to the end of the line or on separate new lines or don't allow the "drop" but please don't "overlay" ("insert" between) whatever is already there!
Also, when I tested "dropping" multiple e-mail addresses from the Address Book, a comma was NOT inserted between the multiple e-mail addresses thus making the entire line of e-mail addresses "invalid". And, it suffers from the identical "overlay" problem described above.
If you have any difficulty understanding the problem, I will gladly provide you anything you need. Just ask.

It appears that the add buttons always copies each E-mail address to a new line so it does not suffer from the lack of comma separators or "overlaying" existing E-mail addresses.
However, that doesn't eliminate the two defects unless Thunderbird disables the "drag & drop" of E-mail addresses which are popular on other E-mail clients. In fact, that is how I noticed the problem: assisting someone with migrating to Thunderbird from another obsolete E-mail client. He is extremely reluctant to giveup his old way of doing things which was "drag & drop" from the Address Book but I am trying to get him to change.

Gestures while dragging objects on Lion 10.7.2

Prior to the 10.7.2 Lion update I was able to drag a file and while holding it activate a gesture to move the file wherever I wanted. It was a really useful feature that helped work faster and I was hoping there is a way to have it again. Any sugestions? Is it a bug that will be fixed (which i really really hope)?.

It appears that at least one developer has filed a bug with Apple on this.
The bug report is mirrored at OpenRadar: OS X 10.7.2: Gestures not enabled while dragging files
(I too find this immensely frustrating.)

Simultaneous trackpad gestures gone in Lion

I used to be able to perform trackpad gestures at the same time as clicking down on the trackpad. This has gone in Lion; now when you click, no gestures can be performed at the same time. Can this be turned back on?
Examples of where I used to use it (and I did it a LOT):
• Click down on a file, then with my other hand I'd do a 4 finger swipe up to show the desktop. This is an easy way to drag files to folder on the desktop/pen drives etc.. without having to do it in finder.
• Same as above, but with a 4 finger swipe down to being up Expose. When dragging files in/out/to/from different applications, it's nice to be able to do this all from the trackpad.
I know for the second one I can just press F3 to bring up mission control, and there's probably an easy solution for the desktop as well, but it just seems weird that since upgrading to the new OS, I actually lose functionality from the trackpad.

I was having the same problem, I found a fix by changing the preferences to without inertia and after a reboot it fixed the problem, I can now scroll with inertia. Looks like a .plist got jumbled.

Copy/paste and drag/drop not working in Mt. Lion

After two weeks of searching, I can not find the hangup which is causing my iMac 27" 10.8 to stop copy/paste and drag/drop following successfully doing the same shortly after startup. In Safe Mode, it doesn't happen, so I'm wondering how to track down this problem (extension?). I have to restart in order to get it functioning again after a short time of working. There has to be some kind of timing, like a program installed with a time limit which probably was forgotten in Lion and then reared its ugly head in Mt. Lion. Any suggestions for tracking this puppy? Or is there a program I could buy to do so?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Copy or drag — do not type — the line below into the Terminal window, then press return:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Use Trackpad for Gestures, Disable Gestures on Mouse?

HI
I would like to take advantage of the trackpad gestures to improve productivity in Lion. At the moment I dont like using the mouse for gestures because I accidentally gesture sometimes when I dont want to, just by using the mouse. So I have disabled gestures on the mouse, and use hot corners and keys for space and app switching etc.
So I thought I could get a trackpad for gestures with my left hand, and mouse in right.
BUT my question is if I enable gestures for the trackpad then wont the mouse be re-enabled too? So then I'll go back to accidental gesturing when using the mouse. So I only want gestures enabled on the trackpad and not mouse, is this possible?
Alternatively I was thinking without gestures on the mouse there's probably not much point in using a magic mouse, maybe I could invest in a much better mouse without touch surface for gestures, then there wont be a conflict. The magic mouse is not that comfortable.
P.S. I dont want to replace the mouse with the trackpad.
Thanks!

@inko9nito it works OK for me. Following from my original post, I have disabled touch gestures on the mouse, and use the trackpad for them. Its working quite well for me. I use the mouse for mouse things as normal (right hand) then the trackpad for switching between desktops (left hand), then all the expose stuff like showing all the apps open etc. Its actually a little over the top to use the expensive trackspad just for those few things, but it does help some, as I dont accidentally do expose things on the magic mouse, nor accidentally activate hot corners that I used to use for expose, and its quicker to do as the trackpad is just next to the keyboard. I'd like to think I can expand its use, but can not see the appeal of using it for mouse things instead of a mouse.

The trackpad/gestures is not working correctly on mountain lion

Hello,
After I have downloaded Mountain Lion, my trackpad/gestures is not working correctly. I cannot swipe with the three fingers, etc. and have to reboot and then it works, but will eventually not work over time. Does anyone else have this problem?
Thanks,
Jeff

I am having the same problem now.
Was okay when first installed on date of Mountain Lion release.
Now I have lost function in Spaces.
Spaces would only work if I used Dock icon to move between Spaces.
Now just run everything in one Space.

Photoshop CS5 "Drag&Drop Place" feature disable?

Photoshop CS5 now allows you to Drag and Drop files into your currently open document and place them as a "Smart" layer. This is quite a nifty feature, and I use it all the time for indesign, but i have grown so use to having Drag and Drop in photoshop simply open the dropped document, that i just cant shake the habit, and am constantly placing files that i simply wanted to open. Now Drag and Drop to open still works if you don't have any documents open or if you drag and drop over the menu bar area, but it's slightly less convenient.
I'd really like to just disable the Drag and Drop to Place, feature, but it would be nice if only placed a dropped file if you were holding down the control or alt key, otherwise it would just open it as normal.

Hi Nick,
I understand your issue, I got the same when upgraded to PS CS5 too, now I just got used to drag the files around the PS UI.
One thing (nor sure if you already know) is that you don't have to drag the file exactly in the menubar to open it instead of place,
you can drag anywhere in the UI that not inside a open doc tab, I drag mine into my layers panel, or any pter panel that is open
at the moment.
Regards,
Dan

Trackpad gestures to double-click/drag to select whole words?

Using a mouse in a TextEdit document, I can double-click a word to select it at once. Double-click/drag alters the selection word-at-a-time. Similarly, triple- and quadruple- clicks might have other handy functions.
What trackpad gestures allow me to do the same word-at-a-time selection?

D'oh! There are mouse buttons in the lower left and right corners of the Magic Pad! So to word-at-a-time select (with the right hand), use the thumb to click-then-hold the lower left mouse button, and the index finger to adjust the selection.

Disable snapping while dragging

i just want to know how to disable the snap while dragging the clips in the time line so i can match the exact lip sync of my video into my music.. in snapping its hard to match it.. Thank you..

AE will quantize to discrete frames and how precisely it does depends on your framerate settings for the comp and the footage interpretation. It's simply inherent in how video works - you couldn't go inbetween two frames, since no data exists there and was never recorded in teh first place. If you are having difficulties, adjust your settings. The only otehr way eould be to use time-remapping/ timewarping, but still, it will never be 100% sample exact. It's just impossible.
