My monitor has a 'viewmeter' which tells you resolution and refresh rates in an active program.
(Viewsonic)
Your monitor might have the same if you go to your menu(menu button on the monitor), while in a game you can check the current refresh rate.
I had the same thing happen to bf1942 but I checked a thread which explained how to fix it.
check this thread out(it's the #4)

this worked by unlocking the refresh rates in the game.
I'm looking for something similar in mohaa.
I can't really say if this happened when I had WinMe never checked it then.
If not, I'll check out what rudedog suggested.
