>I would like to make my form closeable, however, I'd like to warn the user that the form is being closed and allow the form to remain open via messagebox() dialog. I can put the dialog in the destroy method, but the form will close regardless. I can use thisform.release() in conjunction with a form object, but my user will invariably close the form in the conventional Windows fashion.
