I've tried hitting print screen before and going to paint but maybe my print screen button has always been broken. Can never take a screen shot.
Screen shots from the GAME are stored in the ACESHIGH folder as ahss1.bmp, ahss2.bmp and so on. Open them with an art program to view them.
Screen shots from a FILM are different. Setup the shot after hitting pause....remember to move the mouse pointer out of the way

and hit "printscreen" button on your keyboard. This will store the screen shot in virtual memory much like a CNTRL C does. Open an art program and hit "paste" to open the screen shot you too. Remember that only one picture can be stored in the memory at a time. Hitting printscreen again will clear the first picture to make room for the new one.
