Thanks for the reply!
A hard reset does fix the problem. However, it also wipes out all my installed programs along with lots of notes and a few years of info have stored in my Pocket Informant calender. When I restore my PPC with a Spb Backup file, the error comes back.
I suppose, by definition, there's no way to fix a read only memory file - but I wonder how it got altered in the first place? Does SPB Backup also back-up ROM?
