Hi,

Over the last week, my Expose has been acting strange. It will work one minute, and the next it will just stop. This only applies to the all windows part of it. The application windows and show desktop still work fine. What happens is when I click either my dedicated mouse button (logitech performance mouse), apple keyboard shortcut or the dock icon, the screen goes dim but no windows appear. If I restart my computer, the problem goes away but comes back pretty soon. I have tried resetting the PRAM and deleting the system pref plist files but neither solution has worked. Any ideas?

Thanks in advance!

Edit: Btw, my software is up to date.
