Photoshop cs4 extended has been really choppy and laggy for me, far too much for me to work with. I've tried reinstalling, deleting temp files, and nothing. It was fine yesterday, but this morning I turned my PC on to work on some graphics for a little project I'm making, and it was way too choppy. Thanks.
