Thanks nattarious.  I've been following this thread and doing what was suggested.  Thumbs enabled.  I did not have the psicon.dll so downloaded it and put it where instructed.  I still can't see thumbs.  I have a legal, registered app., PS CS2.  Will follow this until it works or no solution in sight.
