 Yes, it is clever, and it appears to work, but I have a question: does 
he lose anything important by not defining his dialog-item-window as an 
instance of lisp-widget-window and/or lisp-widget-top-window?  If the 
answer is yes, can what is lost be safely regained by including the 
aforementioned classes in the inheritance list?
