[Plugin] Leap Motion - Event Driven

Hey I’m using the built-in Leap plugin in UE4 4.15.1 for a VR hot air balloon project, and I had this issue in the past of having a black screen on my monitor when playing in VR. In the VR goggles it works, but not being able to view on screen is a problem. I had the same problem in the past and it had resolved itself I don’t know how, and now I have the same issue again. Anyone any ideas?
