[PRODIG] Corrupted Photoshop appearance (MAC)

[Patrick Baldwin]

Apologies for the cross posting. My problem appears to be in Photoshop CS and Acrobat 6 on a Powerbook. The apps work fine but the toolbars and scrollbars for instance have a psychedelic appearance that goes to some degree if I mouse over the area but returns again next time. The cursor corrupts sometimes in other apps if I mouse over a link or if I move a column guide. I've reinstalled Photoshop to no avail, thrown away all preferences I can think of to be relevant. I've done a Norton virus check on the system and PS CS files.
If anybody has any ideas I'd be very grateful. I can send a screenshot offlist if necessary.
Running 10.3.5
Regards. Patrick.
