Ah, thanks for the link. I was taking out the trash and thinking that I'd do some surfing to try and resolve the mystery.

Mystery solved (although the problem sounds like it will be more difficult...)
But I take back my first post on the subject. Don't send them to me [img]/forums/images/icons/wink.gif[/img]...
