Ive actually had this problem many times on two different computers. Im not sure what the actual fix is but what I always do is a series of unbinding all those controls, verifying files then re-binding.
I do know what causes it for me is turning on my wheel (my view controls are on my wheel AFTER ive started content manager or if I shut down my PC with CM still open. Its strange in the settings menu, pressing those buttons shows activity but in game it wont look.
I wish I could help more, seems a lot of people have had this problem but nobody is sure what the fix is.
