// "Grab" is done while menu systems are up. This has several effects:
// Events are all sent to the "grab window", which does not even
// have to be displayed (and in the case of Fl_Menu.cxx it isn't).
// The system is also told to "grab" events and send them to this app.
// This also modifies how Fl_Window::show() works, on X it turns on
// override_redirect, it does similar things on Windows.
