The problem of course is that if the wheel is too loose, then it may spin too freely and cause its own erratic scrolling issue. In fact, it is quite desirable because excessive clicking with some mice can create a big headache due to all the vibrations. Personally, I find it better because then the mouse has no clicking at all and feels smoother. There’s not a whole lot that can be done about it, but one option is to open the mouse and remove the spring altogether (the one with an end inside the wheel, not the one holding the wheel up). As such, when the wheel is rotated, the mouse things it has stopped scrolling, but when you release the wheel, it settles in the bump, causing a slight rotation forward or backward. This can be exacerbated with age due to wear. The problem is that the bumps inside the wheel (“resting positions”) are not always perfectly aligned with the slits. Moreover, you’ll notice a series of thin slits on the face of the wheel through which a small beam of infrared light passes, and the mouse detects the interruptions as the wheel rotating. This setting makes the mouse wheel move the content on the screen in the.

If you open a wheel-mouse and look at how the scroll-wheel mechanism works, you’ll see that it has a series of bumps inside the wheel and a spring that presses against the bumps to cause the click-y feeling. Look for a setting (in your systems device control panel) called natural scrolling.

To address the problem, you can follow the steps below: 0 reactions. One of the reasons why the mouse scroll is jumping up and down is because the wheel speed has been configured to high. Assuming that the amount of back-scroll is only a single click of the scroll-wheel and not half-way up or down the page, then what you describe is typical of wheel-mice, especially older ones.
