Adobe have released an update to Photoshop CS2 that fixes a few niggles and improves performance in certain conditions.
You can read all about it on the download pages:
It seems a long standing tradition to bring out a 0.0.1 release for Photoshop, this one took longer than other revisions in the past. I have respect for Adobes programming skills so dont see any problems for clients updating their systems with this, it may even solve a few issues you may have.
oops… looks like I spoke too soon:
UPDATE: Adobe forums mention problems for Mac users when printing using 9.0.1 There is a problem with this update and colour management. Looks like a revised update will be coming soon. Will keep you informed.
