>I am trying to solve constant form opening and closing problem where all the forms use the same set of files - a formset is a logical choice as all the forms use the same data in the formset data environment, so there will be no constant opening and closing the data files. So I created the formset, added all the forms, and tried to run it. As soon as you click on the thing to take you to the formset, vivibility of the WHOLE program is gone. So I eliminated ALL the forms one by one, and it STILL does that. Next thing I created a new formset with ONE blank form in it, and it STILL makes the whole program vanish when you try to DO the form. I there some weird access to formsets that I don't know about?

Formset is something I avoid.
I do not DO FORM at all, I have classes and CREATE OBJECT

Anyway even a formset has load; init and activate events where you can place messageboxes
also some code need to create the formset, the line before is logical and the line after too

The first line in click event wherever you click, on the delegate if you use one and so on.
there must be a single line that changes the stuff

Try SET COVERAGE. The output will be a nightmare, but possibly you can follow the way the program goes. (CVP by Martina Jindrová can visualize COVERAGE output)
try SET EVENTTRACKING for events raised.

This is debugging like in the days of yore - without debugger?
