All most always on the first flight when I start to look around(defualt snap view) the view starts to slide in what ever direction I looked till It comes to a stop at max travel. Switch to another view direction and it keeps doing same thing. Only way to stop it is switching to Instant view. Same thing happens in pan view. After awhile no problem. Switch to a new plane and it starts all over again. While it is happening none of the arrow or page up, down, home, keys work. Any ideas?
