Mouse test (clicks, double-click chatter, wheel)
Check that every button registers, and look for buttons that fire twice from one press. Runs in your browser.

How to use
- Click and scroll inside the dashed area with each button.
- Set the chatter window (ms). Two presses of the same button closer than that are logged as a suspect.
- The table shows presses and suspects per button, and wheel steps up and down.
Worked example
Example: with a 50 ms window, a left click that registers twice 35 ms apart is logged as a suspect. A deliberate double-click is usually 100 ms or more apart and is not.
Limits
- No polling-rate or DPI claims: this page cannot measure them.
- A very fast deliberate double press looks like chatter. The log is a hint, not a diagnosis.
- Only mouse input is counted (not touch or pen). Side buttons may be handled by the browser or driver as back/forward.
- Times are the browser’s event times, not the switch’s electrical timing.
