I'm finding that BIAHH will be running fine and then all of a sudden it minimizes to the task bar. If I click on the application it goes back to full screen and runs fine for a few minutes and then does it all over again. HELP????

When i played HH it did the same thing,i found out that i was inadvertently hitting the ctrl or the alt button while in the battle scenes or trying to hit the C or crouch button too fast.
