This sounds, to me, a lot like what happens if the handle() method of your Fl_Window subclass does not call the Fl_Window::handle() method of its base class. So, do your handle() methods explicitly call the ::handle() methods of their base classes? They really must do so, unless you are certain that there is no base class event processing that you need (and in this case, obviously, there is - the window must propagate events to its children.) -- Ian SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
