Cathy,
 
An Error 80 is harmless, and things should continue normally.  The Pervasive help file says
80: The MicroKernel encountered a record-level conflict
The MicroKernel did not perform the Update or Delete operation because of a record-level conflict. For example, station A reads a record, station B reads the same record and updates it, and then station A attempts to update the record. The application should reread the record prior to resending an Update or Delete operation. Alternatively, the application can employ record locks to avoid conflicts.  In key-only files, you receive this status code if the record is moved in the file b-tree after being read and before being updated or deleted. A record can move as a result of other records being inserted, updated, or deleted.
 
With this specific error (most of the 80 series errors), I teach users to wait a few seconds and try their task again and there's usually no problem, and they only have to bug me on the more complicated errors (ones that usually involve path errors or corruption).  I would agree that the increase in frequency is a problem and hopefully it can be fixed!
