What does Mouse Test do?
Check every mouse button, the scroll wheel and — most usefully — whether your mouse has developed a double-click fault. It measures the gap between clicks and flags any pair that arrives faster than a human hand can produce, which is the definitive sign of a worn switch.
How to Use Mouse Test
- 1Click each buttonLeft, right, middle and both side buttons light up as they register.
- 2Scroll both waysThe wheel indicator confirms direction and step size.
- 3Watch for warningsA flagged double click means the switch is producing two events from one press.
Key Features
- All five standard buttons, including the two side buttons
- Double-click fault detection with the measured gap in milliseconds
- Scroll wheel test in both directions, including horizontal scroll
- Click counters per button so intermittent faults show up
- Cursor position and movement readout for tracking checks
Frequently Asked Questions
How do I know if my mouse is double clicking?
Single-click slowly and deliberately. If the test records two clicks less than about 60 ms apart, the switch is bouncing — no human can physically click twice that fast, so it is a hardware fault rather than a habit.
Can a double-click fault be fixed?
Sometimes. The usual cause is a worn contact in the switch, and cleaning it with contact cleaner or bending the tension leaf can buy months. A permanent fix means replacing the switch, or the mouse.
Why does my middle click not register?
Some browsers reserve middle click for opening links in a new tab, so it is intercepted before the page sees it. Clicking inside the test area rather than on a link avoids that.
Are side buttons always detectable?
Only if they send standard back and forward button events. Buttons remapped in the manufacturer software to a macro or keystroke appear as whatever they were remapped to, not as mouse buttons.
