I have just purchased the new EZDOK v2.6 and installed into FSX:SE. I am trying to set up the camera sets with some of my aircraft. Aerosoft A321 at the moment. I am able to set up all of my cameras correctly with various settings however, I am not able to cycle through the views in the virtual cockpit category. 
When I use the preset 'A' key it cycles through the cameras that you can see when you right click the mouse button and highlight cockpit. 

I have also assigned a joystick key to 'NEXT CAMERA IN CATEGORY' this  does the same thing. I have deleted all of the preset cameras in the EZDOK Virtual Cockpit window too. I have looked through the Youtube videos that people have suggested but they do not address my problem. 

 

Any suggestions or help? 

Thanks! 

Sounds to me like you have not deleted the key assignment from fsx control setting, as these have to be deleted to make EZDOK your view controlling system.

That was it. Thanks! I really should have thought of it properly ha.
