"You Need to Restart Your Computer."

[Acidrain9]

i keep getting a gray screen that says "You Need to Restart Your Computer." over my desktop. it actually doesn't happen all the time, but i have noticed that it happends when i launch Maya or when i launch the Blizzard Downloader for WoW. Maya was working fine about a week ago and WoW worked beautifully on 10.5.1. Anyone have any ideas on how i can find what is causing the error? i am not sure but i think it may have started after the itunes/quicktime update. not sure though. any help is appreciated.

EDIT: After a complete reinstall i tried downloading WoW again...i get the same error as above. Anybody have ANY ideas?
