Thanks, Brasas - I was about to say the same in a manner that was a lot less politie - in fact I was so annoyed that I couldn't really write something coherent as a reply to you, but I will grant you that my previous post became a bit of a rant towards the end, and I may have missed an argument on the way to the conclusion. I'll be back later, right now I have a paper to write.
