Bob,

I think I've solved it - just added at messagebox, 'Save changes?' Yes No (if there are any) in the forms Deactivate method. It's not as elegant as I'd hoped for, since the form being activated is on top, but it seems to work. Maybe I should try to put it in the LostFocus method instead.

Anyway thanks for all your help.
