hey miguel,
probably a thinko, but need to correct you anyways ;)
you need to connect to the ::delete_event signal and return TRUE,
so gtk figurs the event has been handled and doesn't do its default
action, which is destroying the widget.
some pretty easy way to do that is:

gtk_signal_connect (GTK_OBJECT (window), "delete_event",
                    GTK_SIGNAL_FUNC (gtk_true), NULL);
