Uh, Hm... But this would be something to check, yes? IOW, you might check step the form through it's operation to see when, and if the table is being opened. And if it is, when is it being closed?

For example, in the cbo's init you might put a breakpoint and check for the alias. If it's not open, then I'd check the de.
