thanks for the the input guys. i have tried Explorer and it is working normally. strangely, i have also used firefox and it has worked normally in full screen for a few games, then if i shrink the window to go look at email, ebay etc. and come back it no longer works in full screen. am not knowledgeable about how computers work at all, but seems really odd that the size of the display would have any reason to affect functionality. weird. guess i am stuck with Explorer for now.
