Originally from ticket #6039.
StarryNight Pro Plus drags to a near lockup when connected to a Meade LX200R scope. It works fine until connected. I also have a copy of TheSkyX Professional which showed the same behavior until I turned off the selection for "allow handbox input". I can't find a similar option to turn off with StarryNight Pro Plus.
This issue has been discussed on the Yahoo board for the LX200
