>Maybe that behavior changed between some earlier versions? I know I fought this problem a long time ago, but it never happened after I changed my code to use "safe select".

Actually, blanking the recordsource preserves the grid, but still has some other problem - which I can't remember. I'm also using safe select (was using it for a few years before I heard it had a name), so whatever that other problem was, doesn't affect me either.

Blanking or even changing the recordsource at design time is a safe recipe for grid amnesia, though :).
