Thanks for the good info.

What is pretty easy to some has many times turned out to be somewhat
difficult for me.  Possibly a dimwit on this end but what were the
pretty easy search terms you goggled with?

Someone not all that familiar with the subject may not come up with
good search strings as quick and easy as someone with a better command
of the subject.

Thanks for the headsup and providing a ready solution... that really helps.
