I have just received my new ASI1600MM. I installed the ASI and ASCOM drivers. I also bought and installed Nebulosity 4. I have not yet taken the camera out under the night sky. I just have it sitting on my desk, plugged in to my PC via USB, and I am going through the Nebulosity 4 manual. I select ZWO ASI Camera in Camera Control. I verify that Nebulosity is talking to the camera because the main image shows light and dark when I point the camera in various directions and click Preview. So, what is confusing me, at this point, is that if I click on Frame and Focus, the Abort button disappears, all of the menu items become greyed out, and I see no way to get out of this mode. The Close application X button doesn't even work. I have to go into the task manager and kill the process to get out of this mode. I'm thinking I must be missing something really basic, but I don't know what it is.
Please Advise.
