Release the instance and close the procedure in the form's onClose event handler.     function form_onClose()        form.oSub.release()        close procedure sub_dele.wfm        return     function form_onOpen()        set procedure to sub_dele.wfm        form.oSub = new sub_deleForm()        return     function PUSHBUTTON1_onClick        form.oSub.readmodal()        return Mervyn.
