In order for me to see what is going on, I need to run the director
configuration with AO Pro, which is the only tool that will allow me to
watch what is changing according to a formulaic progression of wires and
termination points. This is an interesting one with an audience and some
Preparation for WW, SS, etc., kept me busy elsewhere.
I'll give this a shot.
