Actually, using the Print Scr button only saves the image to the clipboard as a bitmap. You have to paste it into a graphic editor such as MS Paint or Paint Shop Pro.
If you have Paint Shop Pro, you can turn Capture on before starting the game and do multiple screenshots with a predecided key (like F12, but you wouldn't use that because it's used by the game itself).
There are other 3rd-party utilities on the Internet that allow you to take screenshots. Do a search on "screen capture" at

Good luck!
