>>While it maybe quite correct to postulate a solution of your own in dismissing mine so rudely, your response gave no constructive information whatsoever.

>It was not rude. It _was_ blunt. And I stand by it. It sounds like you are apparently still under the illusion you *might* be right and that the point is moot. It is not. I suggest again, as I did last night that you try your idea out.
