This appeared when testing with Scheduler 3.3. WHen the dispatcher opens the shutter, the dome does not become slaved. It used to work. Unsure why it changed in ACP 6.
Tested at NMSkies BigDome, Now works properly. Must have been a race cond.
Found one problem - You can't use a script to change slaving because ACP saves and restores the slaving state to what it was before the script was run. Will remove this "feature" as part of this issue.
