I'm running Build 3188 with Windows 98. I'm playing this old game that only runs under Windows 98. The game only runs at 640x480. My problem is that when I switch to full screen mode, the resolution of my Mac doesn't change to 640x480 to match the games resolution, so the game is centered on the screen with huge black borders around it. I have "Change Mac OS X resolution in full screen" checked but that doesn't seem to be working. I'm about ready to go give VMWare a try...
