Jim, just refer back to your own post, read it carefully, then read my response to it equally carefully, and all your questions will be answered.

Or not!

As the case may be....

(It depends on whether you're willing to bother trying to understand anything I said in a reasonable manner or whether you're just out to "win" an argument with me.)

These threads always end up in a hopeless muddle, because too many people are all talking at once, most of them are trying to "win", very few of them are listening with any real intent to find common ground, they're just trying to score points on each other. If I really wanted to talk about this in any depth and have a reasonable time doing so, I'd do it in PMs to Jack, and we could then discuss it as two individuals and probably get somewhere useful in understanding one another's thoughts. Here it's just like being in the middle of a raving football crowd and they're all yelling about something...

And why? Because they haven't got anything else to do at the moment, I guess...it's a way of keeping one's idle mind occupied.

I'm actually rather interested in what Jack is talking about here...and I'd be interested in talking to him about it...but like I say, I'll probably do it in PMs instead.
