*surprise*  I never tried that.  I think i misread the calls to  
gdk_window_destroy() in gtkmenu.c as gtk_window_destroy(), which is  
very different.

Of course, now that i think of it, how could you set one menu into an  
OptionMenu if the menu gets destroyed by popup()?  I must refrain from  
answering emails before my morning caffeine kicks in.  :-)

anguila, if you can give us a minimal example that exhibits the  
behavior you're talking about, we won't have to speculate on what  
you're seeing.

It does, which is why you have to be careful with glade's dialogs; if  
you let delete-event destroy the widget, the glade object winds up  
holding on to zombie objects, which are still alive because the object  
has a reference, but are unusable because they've been destroy-ed.

Well, obviously, this is not meant to be taken literally. It refers to  
any manufacturers of dairy products.
