Boy, that's an argument for a dual OS system! I have only Win2K and WinXP (laptop), but Painter 3D won't run. It has all kinds of problem, beginning with the open file dialog. I also have the full version (only 1 version ever made it to product!). I'm sorry that I can't provide any help. I don't think there is any solution. I'd like to be proven wrong, though. Norm
