Is this still a problem? I apologize this got pushed down on the stack because it is a device issue not an ACP one. If I can help let me know but it's going to be some sort of installation problem. I don't know what the "ASCOM Dome Control Driver" is unless it is the driver for the Digital Domeworks control system. You might check to see if you have the latest. It was changed 2011. I believe the latest is available on the ASCOM site at
