Well, it's not a trivial repro: I just created a form with a grid showing labels.dbf, and replaced one of the textboxes with a container which had a textbox in it. I also set up an ON KEY LABEL so I could trigger the same form again while sitting in the column with the container. I then built it into an EXE and ran it: I could put the focus in that column and hit F9 as many times as I wanted.

Can you come up with a repro that works, as Larry (I think) suggested?
