Your screenshot shows the mount is unparked, with tracking stopped, according to APCC.
There's no way to know for sure what happened from a screenshot, but because the mount is not parked, the driver cannot indicate that the mount has completed parking.
Steve.... What happens if you click the Park button in the ASCOM driver when the mount is in that situation? Does the driver flash "PARKING" and does the mount move to the specified park position?
