So I bought a Steel Series Legendary mouse. It's great and all; nice feel, multiple buttons, good response. Issue being... for some reason, any time I click the middle mouse button (or any button that's mapped to use the Universal Scroll) it causes the camera in DayZ/ArmA to jolt around in rapid succession. I first thought it was the middle button. But then I remapped it to another button and it did the exact same thing. Seems to only be happening in DayZ/ArmA and I have no clue how to fix it.
