So I have a Microsoft Wireless Mobile Mouse 4000 because I don't like my laptop's track pad. I've had this issue with both 3Ds Max and a game engine that works with it called Unity. One second, It all works fine. Then, Two thing typically happen: the thing in the top right of the view port that changes your view angle gets crazy sensitive, and the scroll wheel on the mouse gets super slow. this makes it almost impossible to work with. It's not like a changes the mouse's settings. Can anyone help me out here? Thanks!
