Can't Drag and Drop Anything

I just started experiencing this problem on my mid 2009 MB Pro running the latest Lion. I did a test, and found it happening with the trackpad, my magic touchpad, and my Microsoft Intellipoint mouse (which I broke out just for the experiment. I couldn't "drop" anything I picked up, without clicking "Cmd + ." over the item I was originally trying to copy.

Then I put the computer to sleep, and when I woke it up, the problem ceased.

Thanks for the tip!

Yes, putting the computer does actually fix the problem, but only temporarilly - once you do a total shut down and restart, the problem comes back

Thanks Akash, <command><alt><esc> relaunching Finder worked for me.

If you have issues dragging, uninstall Air Display and / or AirParrot.

There's a good chance that you will be good after that.

Peace !

Thank you Willpower

Removing Air Parrot solved my porblem 🙂

You're welcome !

I'm glad it worked.

🙂

Thanks, I had idea that this application could be related to this issue, but I didn't been sure.

After that when I read your tip, I found this page.

Go to [HD]\System\Library\Extensions

sudo rm -r AirParrotDriver.kext/

sudo rm -r APExtFramebuffer.kext/

otherwise sleep / wakeup method is working for me as well

Thanks

Fantastic !

I think we have established by now, after 10 pages of posts, that the problem is caused by

• Air Parrot
• Air Display
• Splashtop
• possibly other display-related software

We have also established that the problem is resolved by

• Uninstalling the software in question
• Sometimes putting machine to sleep and waking again
• Sometimes re-starting the Finder

At this point I really don't think we need to post anything else here until someone comes up with a permanent solution that does NOT involve uninstalling the software, and does NOT require a constant workaround such as re-starting the Finder or putting the machine to sleep and waking it again.

I'm certain we don't need any more posts that mention the issue being caused by Air Parrot or Air Display, and that you can uninstall the software or use one of the workarounds to fix it. We get it. We understand the cause, we understand the workarounds. It doesn't need to be re-told and re-told and re-told. Ten pages on, and we GET it. No new information = no new posts please.

You missed disabling draglock, in system preferences😉

This post of mine has had 618 readers: http://theotcspace.com/2012/03/11/airparrot-bug-warning/ - it describes how to uninstall AirParrot.

I've started having the drag & drop problem since yesterday. Putting my MacBook Pro to sleep doesn't work and neither does force quitting the finder. Restarting works for a limited time. Yesterday I eliminated Java from my machine (due to the trojan which my mac didn't have) and I wonder if it has anything to do with it? This is really quite annoying!

Also the icons in my dock are froze too.

I logged out of my account and into my test account and I could D&D there. Then I logged back into my main account and then I could D&D there too but I have a feeling in less than an hour it will stop working again.

It works for me too Thanks!!

There is an Air Display uninstaller run it and that will solve the problem!

Might be a solution...
