RE: Gtk::Menu label not showing up after the first time displaying menu

["Jim Barnes" <j r barnes larc nasa gov>]

Bob,

Thanks for the help.  I've found that the issue I'm having is with X-WIN32
and not the GTK::Menus.

I still don't understand what you are trying to do.  If you connected
updateComponents to the idle_loop signal, surely it must do something.
How are you changing your menus otherwise?  The signal to which you
connected merely calls your function whenever it is emitted.  Perhaps
your code doesn't work because the signal is not being emitted?
