Hey Joe :-)
I'll take look at Z3ta for you and get back to you. I can't see this being an APO problem more and ACT issue, so I don't believe the notation would have made a difference.
WRT to the Pro Channel, no you don't have it with LE.
I'm going to keep playing with the split/lower/upper issue, I might fire the question into the main x1 forum as there is more footfall there, so to speak.
have a good trip away.
