Yes, I just copied that bit out of the customize section of my .emacs,
forgot to mention that.

I've since solved the problem – more googling led me to filesets+.el
(which, now that I look at it, is your handiwork), and whatever was in
there solved the problem. But thank you very much for the detailed
explanation (and the patch!). I don't use menus at all, but it's
working as expected now, and I'll be taking a closer look at Icicles
and persistent completion.

Thanks again,
Eric
