Ergonomic Mouse Not Tracking? 8 Fixes for Wireless, Sensor, and Surface Issues

Random cursor jumping has three common causes: a dirty sensor (Fix 1), surface tracking problems on glass or patterned surfaces (Fix 2), or low battery causing inconsistent sensor power (Fix 3). Clean the sensor, move to a solid mouse pad, and check the battery in that order. If jumping continues after all three, USB 3.0 interference (Fix 6) or a failing sensor is the cause.

Trackball skipping at high speeds is usually caused by debris between the ball and the ball cradle that disrupts smooth rotation. Remove the ball from the cradle (most trackballs have a push-out hole on the bottom), clean the three contact points inside the cradle with a cotton swab and isopropyl alcohol, and clean the ball itself. Lint and sk in oil are the most common contaminants. Clean the cradle every 2 to 4 weeks for heavy users. The Kensington Expert's ball can accumulate debris quickly, Kensington sells replacement balls if the original becomes scratched.

Anti-fatigue standing desk mats (foam, gel, or rubber) are too thick and compressible for mouse tracking, the surface moves unpredictably under the mouse during use. Place a separate flat mouse pad on the desk surface for the mouse and keep the standing mat on the floor. Alternatively, use a Kensington trackball, which stays stationary on any flat surface and is not affected by the desk surface type.

Press the button on the back of the MX Vertical to cycle between three device slots. If all three slots are used, the mouse will try to pair with a previously registered device. Switch to an empty slot (one without a device registered) by holding the back button for 3 seconds, the LED will flash to indicate a pairing-ready slot. Then pair the mouse in Windows Bluetooth settings. If the mouse still does not appear in the Bluetooth scan, ensure the mouse battery is charged (low battery can prevent Bluetooth pairing) and confirm the computer's Bluetooth is on and not in airplane mode.
