What is the double click test?
The double click test helps you find a common mouse fault: a worn switch that registers two clicks when you press once. Click slowly and deliberately — the counter should go up by exactly one each time.
Signs of a double-click problem
- The counter jumps by 2 on a single, clean press
- Items open twice or drag-drops fail in apps
- It happens more after a few months of heavy use
What to do about it
Clean the switch, lower the double-click speed in your OS, or replace the mouse. Then re-run the test and the full mouse tester.
FAQ
How do I know if my mouse double-clicks?
Press the button once, slowly. If the counter adds 2, the switch is misfiring.
Can software fix double-clicking?
Sometimes — increasing debounce/double-click delay helps, but a worn switch eventually needs replacing.
