This came up while talking to Ralph yesterday. So I figured I'd post it up. I'm using CS4 on OSX 10.5 1. Sometimes my cursor shifts down about 10 pixels. So if I point somewhere and click, it will actually click 10 pixels lower than where I am pointing. There is seemingly nothing that triggers it and there is no way to turn it off again except for restarting Photoshop. 2. Quite often, when I try to rotate something (shapes, icons, textâ€¦) it will slightly distort the edges, and it takes forever to make it look normal again. Why does it do this and how can I avoid it?
