This patch is supposed to fix the disappearing menus problem on
Qt/Mac. Bennett, could you tell me whether it helps you? I am not even
sure that it compiles for qt/mac, actually :)

It should be very transparent for qt/x11.

I guess I should use some scoped_ptr instead of handling my own
pointer, though.

+  Here is what the Qt documentation says about how a menubar is chosen:
+
+     1) If the window has a QMenuBar then it is used. 2) If the window
+     is a modal then its menubar is used. If no menubar is specified
+     then a default menubar is used (as documented below) 3) If the
+     window has no parent then the default menubar is used (as
+     documented below).
+
+     The above 3 steps are applied all the way up the parent window
+     chain until one of the above are satisifed. If all else fails a
+     default menubar will be created, the default menubar on Qt/Mac is
+     an empty menubar, however you can create a different default
+     menubar by creating a parentless QMenuBar, the first one created
+     will thus be designated the default menubar, and will be used
+     whenever a default menubar is needed.
+
+  Thus, for Qt/Mac, we add the menus to a free standing menubar, so
+  that this menubar will be used also when one of LyX' dialogs has
+  focus. (JMarc)
