Sorry, Joe, for being so tardy in getting back to you.
I ran the full suite of TTP tests, but I wanted to watch what parameters and such are being tested, so I did the tests individually.
On the plus side, I'm most pleased that everything passed with flying colors.
And for reasons that elude me, the -43 error has ceased and all works as divined. That such can be transitory is a mystery. I guess I'll need be more attentive and watchful for unusual events in hopes that clues surface. Unless, of course, you suggest otherwise,
