I'm scratching my head wondering why nobody mentioned just replacing MainLoop() entirely? Yeah, I guess you have to sort of turn your code kind of inside out, but: 

  while (1) {
    if ($Quit) {
      $MW->destroy;
      last;
    }
    DoOneEvent($Running ? Tk::DONT_WAIT : Tk::ALL_EVENTS);
    iterate()           if ($Running);
    save_is_active( 1 ) if (!$Running && !$SaveButtonActive);
  }

If iterate() is particularly long, you still need to spice with the occasional DoOneEvent (I did anyway). The inspiration for this came out of some of the sample code. -- Fred m3047 Morris
