It's still doesn't work when I try full screen mode but the windowed mode is now big enough so thanks for the help.

How do I change the resolution? When I look at the settings, I can't seem to change the resolution from 320x200.

I recently installed the latest version King's Quest II 3.1c but I can't get the game to work in full screen. I got the game to start in a window but it's so small. However, when I try to play the game full screen, my computer seems to freeze for a bit before the game window comes up and then nothin...
