I've only been having this problem since upgrading to CS4. Every single (and I mean literally, every time - even if I just open it and close it) time I quit Photoshop (normally, Photoshop > Quit or Command Q), the blue dot on the dock will still stay there for ~15 seconds, then a notification will pop up saying that it has quit unexpectedly, (as if I had force quit it). Then another window will pop up asking me to send the crash report to adobe. It has never quit properly once. I have tried a fresh re-install of Photoshop and the problem still occurs. Tried repairing permissions as well. Any idea what's going on here? Edit: and I have also tired re-creating the Photoshop preference file.
