I am programming my daily sequence and, when finished and before starting it, I'm going to Mount Tab and then click the "Play" button but nothing happens, the countdown field remains 00:00:00. I have set the park hour to 6:30 (my computer hour is set to UTC) and checked the "Every day" box.
This feature may be very useful because I have a security routine in my observatory that closes the roof and cuts off power from all astronomical devices at 7:00 UTC so an autopark feature before this hour is perfect.
