Just my comment:
Upon browsing this thread which have gone to 14 pages -- has made a lot of circling round & round and reminds me of the question :
"Who comes first - the egg or the chicken?"
Sorry Dfrank , people here have been asking a lot of questions that are not answered as the way they want it to be answered.
It is much interesting for a reader like me to read a thread that is progressing and educating.
