After installing the 10.2.8 update on my 17" PB, file association seems to have been completely hosed. Meaning, all of my files have reverted to generic icons and, if I try to double-click them, I get an error that no "default application" is set. Likewise, applications have either generic app icons or folder icons.
So far I've tried zapping PRAM, repairing permissions, and recalibrating my battery.
Dragging also seems to have died, but from what I've read that may be an unrelated problem.
Any suggestions?
