Yes, I was missing something.  It took just the right incantation on
StartDuckDuckGooglePage (something like ncursesw panel).  I'd call it
a documentation bug/shortcoming.

I am also using the panel library, and it turns out there are
wide-character versions of the auxiliary curses libraries as well.
They are not mentioned in the man pages (as far as I can see).

So the simple solution:  When using libncursesw, you must also use the
'w' versions of the auxiliary libraries (panel, menu, form).  My old
LIBS variable in my Makefile was (roughly):

LIBS = -lpanel -lncursesw	# Wrong (mixing versions)

It needs to be:

LIBS = -lpanelw -lncursesw	# Right (all are 'w' versions)

and then everything just started working.  I should probably report it
as a documentation bug...
