It was, in fact, V1, your thread that prompted me to post as I did. Not withstanding data indicating "not to worry", I'll try be to prudently paranoid and keep my tool cool (a term I've not used in a great many years).
BTW, your tutorial was very helpful. Many thanks!
thx. If you still have a question or concern that I didn't address, let me know. I thought you were still looking for an answer to something.
