The app has been installed for approx 9 months and this was the first time this happened and it hasn't happened since. Fragmentation was 0% and Scandisk revealed no bad sectors or file segments. For now, I'm chalking this one up to a cosmic PITA and will dig deeper if it ever happens again.

>>PMFJI: When I have seen this problem, its really that the error message is misleading --> it means "alias not found" - IOW: the table didn't get opened for which the alias is needed, and it thinks the alias is just a memvar. So, as stated before, I suggest looking at corrupted table and/or index that prevents the table from being opened and then the code that refers to it uses the alias -- which is no longer valid since the alias and current table don't match...

Hi Colin:

Well, it was worth a try. Good luck & I hope it doesn't happen again...
