I am running Windows 7 64 bit in Parallels Desktop on my MacBook Pro. The game runs fine, but only takes up about a quarter of the screen in the center, which is surrounded by black. I've tried running the game in XP and 95 mode, but it doesn't help the problem. Any suggestions, or is this just what I'm stuck with for right now?
