Thanks rharv, very interesting.

I'll do some experimenting with that.

I love BB and RB - it's been a lot of fun for many years and I don't know what I'd do without it.

But I have a flat spot on my forehead from beating my head against the wall quite often, and then another flat spot on the other side where I slapped myself very often and said "rats, I should have known that". But your hint saved me from that part because I didn't know about that.

Thanks again for the advice.
