The ever-patient Michael is being quite nice to you, pete, so, in good cop-bad cop tradition, let's say, once again, that every post you post betrays the lamentable fact that you haven't a clue what you're talking about. I'd really love to ask you what you think it is I'm supposed to have evaded, but I just know I won't get a sensible reply.

And here we go again: i have come across this before and i dont have time to look up stuff right now

Well why's that, pete? What are you doing that's so important that it forces you, time and time again, to post here totally unprepared? Or are you, as I think you are, a lazy bugger who only deals in received wisdom from near-lunatics?
