Paul:
And I thank you for your reply -- you've been much kinder than most (on and
off-list). :-)
True the subject line was a bit misleading, but that was intentional. Bait
causes more fish to rise.
I've received the answer several times over since I posted the problem, but I
wasn't looking for a solution because I already had one.
What I was looking for was an explanation, which I "got". I hope the answer
remains with me longer than the bandages do. Asking questions in this group is
like trying to feed alligators while being waist-deep in the swamp. :-)
Thanks.
tedd
