Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Appendix "D.2 Table of X Resources for Emacs" of the Emacs
info manual states that:
| `menuBar' (class `MenuBar')
| Give frames menu bars if `on'; don't have menu bars if `off'.
| *Note Lucid Resources::, and *note LessTif Resources::, for how to
| control the appearance of the menu bar if you have one.
Yet, "on" produces *no* menu bar; you have to use "1" to
enable it. "off" on the other hand works as expected (maybe
silently cast to "0"?).
