I have a strange problem. that only occurs with the new 60 dets. Sometime when i go to click on a movie. my main monitor will free out (almost likle switch resolutions or zoom in). I can still click on the windows or whatever. but when i do they just go behind whatever other window i have open. i have to hit the reset switch because i cant actually activate any of the programs. This is kinda hard to explain. 
edit: also have latest drivers/bios/firware for everything. Its not the cards. because ive had the same problem with a 4200,5900, and 6800
