It is very easy to recreate the lockup problem.
1. Start APCC pro, connect to Mount, connect to ASCOM
2. Use AP V2 driver to slew the telescope.
3. I can see the APCC pro locked up after a minute. Mount slew back to Park 3.
See the attached image after I tried to slew to NE.
I can setup teamview for you to look at my setup. It is cloudy now.
