The program hangs and I can't even interrupt it to suspend and see which record it is sitting on. I have a wait window just to show me which step the program is currently at, and I can't get that to disappear as well. It's reall weird!!! I can try using a DO While NOT EOF(), but I don't think the SCAN is a problem. As I said, it's been running perfectly for 2 years now. How else can I check for corrupted tables. Sometime I do get an error on a temp file that I use when merging the records. It says 'Not a table' when trying to use this file. I replace it with a good copy of the file and it works fine. But it could be related, do you think?
