hi Lamda09a, and welcome to sevenforums, you'll like it here,
i had a similar problem back in my brief vista days with a samsung monitor - it didn't like any program going fullscreen - especially movies, it would flicker like crazy.
a visit to the manufacturer's webiste and a quick driver
/profile download sorted it out - the one and only time i've needed to download a monitor driver ever
, i think. luckily the same monitor has no problems in any of the 7s that i've tried.
hope this helps, if not, come back here!
