Lum,
Interestingly in the way that Google Groups works, my posting
was lumped together with another thread on the same topic
from 1999 where you were discussing that exact item. No time
to read it now as work calls but it should be an interesting
read later.

BTW, I know it's been said before but perhaps not by me, thanks
for hanging around this newsgroup and giving us help with our
habit... I mean hobby.
