Hi Bob,
We have discussed this issue before, but still not resolved.
The problem is that any park command sent from ACP script to ASA Autolew, parks the scope, but tracking continues. You have to unclick the ACP console check-box to stop tracking.

Does the ASCOM park command assume that the driver will also stop tracking?
Maybe ACP is thus not sending a command to stop tracking, but Autoslew is waiting for one?
Is so, I will take it up with ASA.
