Do not waste your time arguing with Stu. He has the brainpower of a goldfish and a pathalogical inability to admit when he's wrong.
Thanks for the "headsup" on "Stu". Haven't encountered him before - but have run across his kind - the QC mentality, a bunch of times in various types of endeavors; missle development, software development. They are necessary in the right setting - problem is they think they belong in every setting - full time all time; peering over your shoulder offering nothing but criticism.
Thanks for saving me from redoing my answer to his last post - I had it all typed out and inadvertently wiped it out. I was about to retype it when I got your post.
Of course Stu would probably say the inadvertent wipeout was caused by a lack of .....yep! OC!
