I have the Digital Dome Works hardware. From the web browser UI I can open the shutter, and the UI as well as the dome control window in the ACP UI both show that the dome is slaving, but it does not, even with Sidereal Tracking checked in the ACP UI (I thought that might be the reason).

"DOME" is showing as solid green in the ACP UI.

Periodically, Dome in web browser UI (under observatory) either shows solid "Slave" or flashing "Slew".

In the web browser UI, messages in the upper right read:

Opening shutter...Dome unhomed. Slaving enabled. Dome will now follow telescope.

Slaving just doesn't happen.

Thanks in advance for your help.
