Yep. This should have found its way into my gtk nits post a few days ago too.

The problem is that teh default action for the window delete signal 
handler (i.e. the FALSE return) is to do nothing. I think that a better 
solution would have been to make the default destroy the window, and for 
signal handlers that wanted to catch the signal to return TRUE. This 
would be consistent with many of the other event handlers in GTK - FALSE 
means "I didn't handle it, pass it up to the next guy", TRUE means "I got 
it, return now".

In the meantime, add this code for all windows created:

/* A signal handler for the window manager delete signal. Returns true
   so that the window gets destroyed. */
static gboolean
handle_delete (GtkWidget *widget, void *dummy)
{
  return TRUE;
}

gtk_signal_connect (GTK_OBJECT (window), GTK_SIGNAL_FUNC (handle_delete), 
NULL);

Good luck!
