Ray, The only difference that I see is that you are connected via TCP LAN/WIFI while I am connected throughAndy, I also tried using a serial port connection to the mount, which to APCC is the same as the virtual COM port in a USB connection. Again, there was no unexpected behavior.
The only thing left is for you to use the APCC log zipper and zip your APCC and ASCOM logs from last night. It is important to include both logs, so make sure that you use the APCC Log zipper and not the ASCOM Log Zipper (they are two different utilities). If you could provide me with a download like to the zip file, I'll take a look.
Also, what is the exact version number of NINA that you are using?
