I use emacs as a TeX/LaTeX editor with the excellent AUCTeX mode, but when I upgraded to Emacs23, I lost AUCTeX menus!
I usually don't use those "rookie menus" but it's really useful to quickly recover a shortcut or a command name.

I found the clue at Life Algorithms: just add
export GDK_NATIVE_WINDOWS=1
to your ~/.bashrc.
