>But it seems there is now way to have one form (not in a formset) call a method of another form.. Hope this is something that can be addressed in a future version.

You certainly can call a method from one form in another form wihtout a formset, you simply need a reference to the form that contains the method.

>in a form; how can you stop the closing of a form?
>ie: if the user clicks the "X" to close the form; i need to do some processing; and based on that; allow the form to be closed or not.

When the user uses the X to close a form the form's QueryUnload fires. In there you can check what you like and issue a NODEFAULT to stop the form from unloading.
