Inherited Function Key Behavior

[dhk <dhkuhl optonline net>]

My GTK program seems to have inherited some function keys from
somewhere.  When I press F10 the menu in the menu bar opens and when I
press F10 again it goes away.  The same behavior happens in the
gnome-terminal.  When I press F10 my key press event isn't even called,
but F9 and others work.  Does anyone know what causes this and how to
override it?

Thanks,
