2003-11-04  Marco Pesenti Gritti  <marco@gnome.org>

        * src/ephy-window.c: (edit_menu_show_cb), (edit_menu_hide_cb),
        (init_menu_updaters), (setup_window):

        Yet another sensitivity update strategy. Set sensitivity
        on menu show and reset it on menu hide, so that accellerators
        ever work.
