为什么我的鼠标滚轮垂直滚动步骤重置为“ 1”？

Question

Every time I fire up Visual Studio, my vertical scroll settings for mouse (and the touch pad as well, in case a mouse is not attached at that moment) resets to "1" from "3". I set the scroll step to "3" and after coding a couple of lines, testing and debug, the scroll step size resets to "1" again.

Any ideas?

system info: Samsung notebook, Windows 7 home basic, Visual Studio Express 2012.

note: My code has nothing to do with mouse or any other hardware.

This is not an exact solution, for to phrase it as an exact solution I've got to figure out the main reason at first; but I've overcome the bug by just removing the mouse driver and let Windows to manage the mouse via it's generic driver.
