Newbie question

Hi
This will clearly be user error
After some months of playing with my actual equipment and getting some progress I’ve decided to do what was recommended and work through the tutorials using the wiki as a guide

I didnt get far and hit an issue
Setting up a Camera Simulator
I chose ASCOM Camera, then clicked the ASCOM button to choose a camera


From this I chose Camera V3 Simulator
In the dialog it shows as ASCOM.Simulator.Camera
However if I click on Properties - nothing happens and I cannot set any parameters
What am I missing?
Regards
Mike
