Thanks for bringing this up again. Having followed all of the old threads..I was still confused!! NOW..I think I'm clear, finally!
For those who hate seeing repeated subjects: long, old, convolutedthreads are NOT the best sources for information. There is a need for refresher threads such as this to re-affirm what some may have thought, or not thought in the past. A bit more tolerance would be nice!!! Nobody is forcing anyone to read threads for which, already, he may know the answer. For some of us, old news IS new news!!!!
