Dirty event not working

[bllgnn]

I have 2 main forms with controls bound to the same query. Each form has a subform based on different queries. One main form and both subforms respond to the On Dirty event, the other main form one does not.

I have put a breakpoint in the Form_Dirty procedure on each main form, but when I change data in a bound control on either form, it is only encountered on the first main form.

Each form is based on the same query, but both forms are never open at the same time.

Does anyone know why it works with one form but not the other?

This problem mysteriously disappeared a few days later without any conscious effort opn my part.
