Subform behavior

[jimcarroll]

I have a subform on a tab control of a main form, based on a query.

The subform consists of a combo box.

The problem is that when I place the focus in the combo box, the main
form moves to the next record. That seems wrong. Then, if I use the
main form's record selector to move back, the form moves back TWO
records and not just one. Really strange...

How can I keep the subform from triggering this "move next" action
every time I click on its combobox? And what's up with the "two jumps
back"? I suspect it's because the subform is on a tab control -- but
it's a busy form and I need several pages.

Thanks.
