Mouse Hardware Troubleshooting
Unwanted Double Clicking (Switch Chattering)
Mechanical microswitches (like Omron 50M) can develop oxidation or worn metal leaves over time, causing a single physical click to register as multiple electrical triggers under 50ms.
Scroll Wheel Jumping or Inverted
Optical and mechanical rotary encoders collect dust and fibers, causing the page to stutter or jump up while scrolling down. A few drops of isopropyl alcohol or canned air in the wheel well usually restores accuracy.
