Hmm.. I would test with a fresh install just to rule that out (since you mentioned you hadn't done that) though I don't believe that's the issue based on your above observation. It's more likely something to do with your display driver not being able to handle the resolution or refresh rate changes between whatever MAME game you are running and native Windows (though only for your VGA device as you pointed out). Try upgrading your display driver, or use a different video card?
