I have the same problem -- and the same graphics card. Do you have a Toshiba Satellite running windows XP? I was able to fix it by right clicking on the program icon and selecting Properties, then the Compatibility tab, and then checking the box for 680 x 480 resolution. everything worked smoothly, although it kind of sucks that the image is so big you have to navigate around with the slider bars. It also worked when i checked the box for "run in 256 color mode", though not as smoothly.
