[Solution] Problem for spinning soldier when pressing Shift key

So after trying out BF4 again after a long break, I had the recurring problem that, whenever I pressed Shift, my soldier started spinning out of control.

I found out that if you have Mousekeys enable on shift, or Stickey key enabled, BF4 will glitch.

The solution is to go to control panel, search mousekeys, and disable any sticky key or option that uses shift.

Go to Control Panel\Ease of Access\Ease of Access Center\Make the keyboard easier to use

Hope this helps
