Anybody ever have this happen? I'm cruising along, editing and testing a form in the form designer, and when I try to run the form, I get dumped immediately back to the form designer -- and the table (it's a single-table form) is gone from the data environment.

The first time this happenned I assumed that I was just being a spaz and accidentally deleted it. It's happenned several times since then, when I definitely didn't have the data environment open.

Aside from the inconvenience, is there anything I should be worried about?
