Today I was running Adobe Photoshop CS3, and it was the first time since I needed to format and reinstall everything. Today I noticed, for the first time opening the program since then (And a new Motherboard) that as I began to edit the picture using the Blur tool, Sharpen tool or even a "Brush" type, that if I drag to slowly, i begin to drag "blocks" of the picture around. It fixes when I zoom out, move the picture or refresh it, but otherwise the glitches stay there. Might anyone be able to tell me exactly what might be going on with this? I have the latest video drivers.
Oh, I should mention, I tried a few other picture editing programs, and its not happening to them, which is weird to me, you'd figure if it was a 2D problem I'd see it else where, but I used 5 other editing programs I have and there as no glitches or blockey-ness going on.
Any help would be greatly welcomed.
