Hello, i've got a problem for quite some time with photoshop. Everytime i do a couple of brushstrokes, especially with brushes larger than 50 pixels, the program locks up my computer. It worked just fine before, but then my video card broke, and i had to use my onboard card that takes 32 mb's out of the computer RAM. When i tried to use a friend's card, photoshop worked just fine! Please tell me how to fix this problem! I've tried photoshop 6, 7, cs and cs3, none of them work, they all crash.
