Also, when it does crash, it 'forgets' whatever changes were made to the main table since the program was started. IOW- if someone goes in and changes some data and the program crashes, it reverts. It also leaves the date/time of the dbf file at whatever it previously was. The error also doesn't happen (at all?) when I'm tracing the code. I can't seem to make it happen. However, in both cases the disk activity jumps up as does the processor usage...
