Getting a menu inside of a window is not that easy. You will have to
hack through NSMenu a bit. If you know what you are doing this is fine,
but don't expect to get every step explained by this mailing list. We
don't even know, whether you plan to give the resulting code back to
GNUstep.

The problem you are facing now is that setMenuRepresentation: changes
the superview of the NSMenuView, so it no longer is inside of the main
window, but now it is in the internal window of the menu. You could
simply store the super view before you call setMenuRepresentation: and
reset it after that. You surely will face a new problem after that one,
what are you plans for dealing with that? Wouldn't it be better to
address this problem more systematically?
