Phillip,
Mea culpa, I guess you are right. In fact in another (main) part of my
program I do construct a dynamic menu depending on the contents/layout
of the file system. This comboBox is only in a preferences panel and
out of curiosity I changed an ordinary textField into a comboBox and
populated the box first from IB and next from a "factory" defaults file
in the bundle (if present).
So what you are saying is that comboBox menu items ("under" the box)
should either be grayed-out (if that were possible) or always be
functional/valid.
Which brings me to a thought I had previously: why not make the
comboBox menu more like an ordinary menu? Same background, for
instance, same separator items, possibility to gray-out etc. etc.
Anyway, thanks for your answer.

I realize that this is not actually an answer to your question,
but.... Why
not populate the menu dynamically and only put things into it that are
valid
for the current conditions? It's usually better for program
maintenance and
certainly better for the user.
My number one complaint when working on Windows systems -- even more
than BSOD
and virii -- is that much software on that platform is sloppy about
engineering out invalid choices. (I absolutely hate being offered a
choice
and then being told I was wrong to think it should be functional...or
just
having it quietly do nothing.)
