Drone Camera and Click spots

I have seen videos of the drone camera in use, and folks seem to be able to make use of click spots in this mode. On my installation, I use an XBox game controller to move around while in Showcase mode; but find that while my mouse cursor will change to a ‘hand’ when I try to open doors or click switches; they don’t respond.

How do I make it possible to make use of click spots while in ‘showcase’ mode?

Thanks in advance.
