please note that Alt-F9 is *NOT* a Far command it's intercepted by the X11 window manager as beeing a maximize window command (so using the maximize button on window has the same effect) (Alt-F9 has another meaning in Far) A+
Maybe in your window manager Alt+F9 is intercepted, but not in mine ;)
Thus Alt + F9 is intercepted by Far directly here. Thus the issue holds true.
