It's a G4 800MHz single processor with 768MB of ram. I've run fsck-y a few times and repaired permissions twice more and at least Photoshop works now but the desktop and dock are still misbehaving sometimes on restart and now Netscape 7.02 launches but nothing at all shows up on the desktop yet 7.1 works just fine as does Camino Safari, Omniweb, Mozilla and Opera but IE's preferences were back to default, go figure
Also should note that when I first restarted after the update and permission repair the dock only contained the generic set, had to rebuild it to it's previous state and that seems to stick.
