Photoshop Elements 12 stops working a few minutes after starting the application

Question

I need technical support for this problem.

Answer 1

This is definitely a Spaces/Mision Control-related issue - I disabled the keyboard shortcuts and the issue goes away. Of course this is not a solution as I need keyboard shortcuts to be productive.
I think it has something to do with the control key being mapped to multiple functions. This issue cropped up for me only after upgrading to Lion. When I upgraded to Lion for some reason the left control key took on the same function as the "Application Windows" function in Mission Control (which is assigned by default to F10). I went into the Keyboard shortcuts settings and can't see where the left control key is being mapped so I can't remove it. I think for me this is the cause of the spaces keyboard shortcut issue - something in the system is grabbing onto the left control key function and fighting with Mission Control when I hit control-1 or control-left to switch desktops. When this happens the keyboard no longer responds to most keypresses and I have to kill the dock to restore functionality.
If anyone else could confirm that their left control key is invoking the "Application Windows" function I think we can narrow down the issue and possible come up with a solution. Please report back and I'll do the same. Also, Apple, please take onus and address this issue as I believe it's not related to third-party software.
