The graphics/windowing system that WordGenerator uses is Tk,
for which two implementations are available under
MacOSX. One implementation uses X11 as the underlying
graphics and window system. This version of Tk is almost
identical to the Unix version for which WordGenerator was
written. If you use this version of Tk, you should find that
WordGenerator looks and behaves just as described in the
documentation, which is based in the first instance on the
GNU/Linux version of WordGenerator.

The other implementation of Tk for MacOSX uses Aqua as the
underlying graphics and window system. This version of Tk
provides a more native Macintosh look and feel, at the
expense of introducing differences between the look and
behavior of programs under MacOSX and on other machines. In
particular, the Macintosh user interface guidelines, which
the Aqua implementation of Tk enforces, allow only menus,
not commands, to be placed on the menu bar. As a result, if
you are using Tk-Aqua, the File, Search, Character Entry,
and Help menus will appear on the Macintosh menu, while the
Generate, Abort, and Choose Font buttons will appear in a
row at the top of the WordGenerator window.
