X-Keys and Kensington Trackball buttons no longer work in N7

Suddenly these stopped working for me in N7.

On the Kensington Expert Mouse: Only Click and Right Click work, no other programmed buttons work (e.g. “double click”). Works fine in other programs.

On X-Keys: Works fine with Nuendo 6.5 but nothing works with Nuendo 7.

Trashed preferences and still no luck. Reinstall?

Solution: I was running Nuendo “as Administrator” on Windows 10. jBridge prompted me to do this. I turned that setting off and all works as expected again.
