Hi Lawrence,

Yes, I'm still working on this. I'll be away this weekend,
but hope to leap back in to the fray after that... shouldn't
take long; problem has been getting time to do it! (I've also
been tackling about a dozen items at once. This is a no-good
way of doing things; I feel as if I'm entering what the
operating systems folk call "process lock", where you try to
do a zillion things simultaneously and none of them get done!
Not an unresolvable problem, of course...)
