Thanks, but the mouse must only invert when it's bound to the camera, otherwise, clicking on buttons will be really hard.
I'm coping when walking but I have another camera-related request - when driving (maybe this is because the mouse is not inverted and I adjust the wrong way?) I find myself looking up at the car from under the road. Probably it makes no sense to allow the camera to move independently of the car? usually driving has the camera floating behind the car looking forward all the time.
