>I would like to find a way to close forms or formsets beyond the one that the user is currently working on. Users often open another menu choice without closing the first. This can then become several forms deep. By using formcount and _screen properties, I can determine that a previous form is still open, but I am having a hard time determing if it is a form or part of a formset, which I think I need to know to release it. Perhaps there is some code to close the last form/formset as the next one is opening.

Your interface sounds a little awkward, but anyway, something like:

if type('_screen.activeform.parent.class') = 'C'

should distinguish between formset/form...
