David -

I checked, and they aren't *supposed* to be using anything else (Other than VFP7) to access the data in our system.

Why would this matter? Do these other products have a history of corrupting VFP tables? We thought it was too odd that seemingly random integer fields keep changing by EXACTLY 128.

BTW, we also saw currency fields unexpectedly changing. But those fields changed by trillions. It was asy to spot those errors. :)

>>Oh, one more thing: we tried putting update triggers on the data, but the triggers haven't fired. The records affected were added 2 years ago or so. They hadn't changed at all until a few weeks ago. Our system is set up in such a way that these records really never change.
