Hello Randy,

thank you for testing and your comments!

Concerning the segfault, I already have a version 8 prepared but wanted
to do more testing before disturbing people, again.

The initialization and operation of the serialized menu was ugly and
wrong.  I did not notice segfaults so far, but I can imagine the
segfaults you noticed are caused by this, because the code you tested
did not operate only on propper initialized array elements.

Before sending out version 8, I would like to include your other
suggestions as well, so could you please try the attached patch if that
also produces the segfaults?

Thanks,

Dirk
