Folks, can we please stop taking every opportunity to microanalyse every word, every comma and every question mark? Most of what's in this thread has stayed polite, if not exactly friendly in places but in the last couple of dozen posts it's starting to turn more into 'aha! I see a minute loophole in what XXX said and I'm going to tear him/her a new one until I make him/her look like a fool." Everyone's made their respective positions perfectly clear and it's obvious that were never all going to agree on it. Kev.
