I ask questions on this newsgroup so infrequently that
it seems a shame to answer my own question, but there you go...
Thanks to the guys at RSI, who appear to get to work
even before I do, I've figured out what my problem
was. It's the ol' Hershey font is -1 instead of the
normal 0 for the default case problem. If the initial value
of an ENUMLIST property is -1, then it doesn't put anything
into its "default value" space initially.
Now I've got it all sorted out and the property widget
works like a champ. I'll be working on a training program
today, though, to get all my users used to using FONT=0
if they want a Hershey font. :^)
Cheers,
David
