You've been insulting me incessantly over this and other matters over the last few days, Nigel. Your input has been a series of niggles, Niggles. Just make your points and back off is my advice. That's what I've tried to do in this thread, but, as we can all see, your agenda is different. If you don't want the piss to be (deservedly) taken out of you, just take the advice. You do appear to be rather sensitive, unlike me, so why invite the hurt? And bear in mind that your allies here are few. Nighty night! :-)
