Had that happen a few times.  No idea what causes it though. I just reboot computer and radio.  Everything comes good.

After watching Daniel, W5EKG's You Tube video, I had SatPC32 and the IC-9700 working beautifully on the first try. (Thanks, Daniel!) The radio frequency tracked the software real-time just like it should.

However, after playing around for a few minutes (changing satellites, turning the main tuning knob, etc.) The radio suddenly stopped following the frequency changes from SatPC32. The frequency intermittently updates after 10-20 seconds accompanied by the frequency on the radio display flashing white from MAIN to SUB for a brief moment. Usually nothing happens until I choose another satellite then the frequency updates once then...crickets.

Pertinent information:

Windows 10 IC-9700 Firmware 1.05 Icom Driver Version 1.30 Baud Rate: 19200 (Tried dropping it to 9600) The AFC is turned off. Tried rebooting the software. Tried rebooting the computer, etc.

Any clues?
