Thanks for that.
Many thanks Neil,
I appreciate your reply, informative, helpful, and explaining the situation without making me feel like an idiot. The problem I have been having - and why I have been getting so wound up in regard to:
can be demonstrated - I think - at this thread: showthread.php?t=4994 , where such an enquiry leads to a maze of misinformation - and not the straight-forward informative reply that you suggest. I admit to my part in that.
I think you are absolutely right, and in any thread, a reply like yours will be entirely welcome and appreciated by me. It just doesn't seem to pan out that way with some of the other threads.
Anyway, thanks for that. Now I have to go off and contemplate the depressing prospect of climbing off my high-horse and showing a little humilty following some disaterously over-reactionary posts I've made, and (still only slightly at this early stage) regret.
