VR Gunner: Guns shoot when window out of focus

[Nealius]

In VR it's common for the window to go out of focus when trying to click something in the cockpit, or maybe some other background program does something. When this happens, the human gunner's gun will start firing non-stop until the window is brought back into focus.

If you have binded MB1 to fire weapons it will happen. DCS will register click and execute, but will not be able to stop because it is no longer receiving inputs. Two ways to have it fixed: unbind mouse or select cursor confined to window in VR tab
