Thanks for the quick response!
The reason that I considered not handling the event is the fact that
I've got the pop-up trigger associated with a non-active list. If I
don't try to make a new label on the form (or simply don't handle the
popSelectEvent) the system takes care of changing the label on the
pop-up trigger for me. Do you know why I might need to take care of it
manually with the CtlSetLabel() after I've used FrmNewLabel to add
something to the form?
