With some trepidation, based on the above posts, decided to download CS3 (the beta had run out yesterday). I was in the middle of processing a shoot when the beta ran out and I have gotten so used to PS3 that I did not want to go back to PS2. Following the Adobe uninstall directions, it went flawless! I was frankly surprised because I have, in general, really bad computer gremlin experience and had had a fair amount of issues with both CS2 and CS3 beta on this computer. Maybe, for a change because of the above experiences, I actually read and followed instructions for a change or Adobe has tweaked some things in the meantime?
