Hello. I have an ATI 4550 running on a windows 7 64 bit system. I downloaded and installed the latest drivers. Two monitors are connected, one on VGA and another on DVI. I am running extended desktop. If I am watching full screen video via flash on one desktop I can view the other desktop fine, but if I click on anything, the video reverts to normal size (not full screen.) I don't remember having this issue on my ATI 6150 system. Thanks.
