I have no idea if this is the same problem as you, but since the last update, when I hold down my right-mouse button to move the camera view around the cockpit, nothing happens. It had always worked before, but just stopped. The ‘fix’ if you want to call it that was to toggle the middle mouse button. When I clicked that, it began to work again. Of course then the camera went all over the place as I moved my mouse and I had to click it again to toggle it back, but at least it worked.
If that’s not your problem, I apologize. I hope this helps.
