Thanks so much for letting me know! I haven't downloaded many brushes yet but I did go kind of wild with layer styles (like a kid in a candy store!!!!). Shall move some of the less appealing ones into a standby folder. Haven't had any problems yet but don't want any either. Thanks again.

Have you checked out all the goodies at the Adobe Studio Exchange:
