It works fine for me in 9. In 10, I get a beep, and empty 3D window, and that's it. Like an error, but nothing in the report. No files generated. Tried internal and LW. Weird, I know a made a small VR scene in 10 about 3 months ago.
I had no trouble actually linking the cameras, though. Camera tool active, click on the center of one, then the center of another. Mouse up or down doesn't matter. If you click on a camera and then in empty space, you get a new camera and a link.
