No, there are not part of a formset and no, I do not use LockScreen.

Form A is modal by the way, so that may be my problem. I would try to put it modeless and run the form again to see if it run OK.

I would post the result later.

>Are these forms part of a formset? You can't mix modal and modeless forms inside a formset, even though it would seem to be a natural use of them to have a modeless parent launch modal child forms but you can't do that.
