Steady on guys. John's explanation was clear enough and helpful as far as I am concerned. Norm was no doubt on about the other stuff that turns up here as a result of cross posting ( or is it also multi-posting?) which has nothing to do with engineering and continually attacks someone who, it seems, has questionable ethics and behaviour. Such is the way that things work but I too would rather folks thought a bit more before hitting the Reply button. I also wish folks would learn to snip the irrelevant parts of posts. Some get tediously long. Yes - I know - learn to live with it!
Cheers
Henry
