It can't resize or maximize. I'm on windows 7 64bit.
I remember programs where fans have made simple directx apps that launched fullscreen-only games in a window. Is there any app or script I can run that might work with this game?
Here is a workable solution I found exactly a decade ago in 2003, that still works today (tested on Windows 7 x64).
It works for most fix-sized games I've tried it on, including Diablo 2, Starcraft 1, and both Governors of Poker, including virtually every windows screen, including popup message boxes.
Turn down your desktop resolution to a closer match to the window's size.
Perhaps right-click the icon-->Properties-->Compatibility tab and check-mark "Run in 640x480" and see if that suits it.
