Is your mouse double-clicking by itself?

Accidental double-clicks are one of the most common mouse faults. Inside every button is a tiny metal switch; as it wears or oxidises, a single press can “bounce” and register twice. Files open when you meant to select them, drag-and-drop fails, and in games a single shot becomes two.

This test flags any two presses of the same button closer together than the threshold (80 ms by default). Even fast deliberate double-clicks are usually slower than that, so a warning on a single click is a strong sign of switch chatter.

How to test

  1. Click each button slowly, one press at a time, inside the test area: left, right, wheel (middle), and the side Back/Forward buttons if you have them.
  2. Repeat each button 10–20 times. Any red “unwanted double-click” message means the switch is chattering.
  3. Scroll up and down. Both counters should rise smoothly; jumps in the wrong direction suggest a worn wheel encoder.
  4. Move the mouse in quick circles inside the area to measure polling rate.

Fixing double-clicks and dead buttons

  • Try another USB port, a fresh battery, or re-pair the receiver — weak power causes erratic clicks.
  • Check Windows: Settings → Bluetooth & devices → Mouse → Additional mouse settings → make sure “ClickLock” is off and double-click speed is reasonable.
  • Blowing compressed air around the button or clicking firmly 20–30 times sometimes clears oxidation temporarily.
  • Many gaming mice have a “debounce time” setting in their software; raising it can hide chatter.
  • Permanent fixes are replacing the micro switch (for those comfortable soldering) or using the warranty — chattering is a common warranty claim.

Polling rate explained

Polling rate is how often the mouse reports its position to the computer: 125 Hz (every 8 ms) is typical for office mice, 1000 Hz (every 1 ms) for gaming mice, and some new models go to 4000–8000 Hz. Higher rates feel smoother on high-refresh monitors. Browsers can limit how many events they deliver, so the measured value may read lower than the true rate on some systems — use a supported browser like Chrome or Edge for the best result.

Click speed (CPS)

The CPS test counts left clicks over 5 seconds. Casual users land around 5–7 CPS; competitive players often reach 8–12 with special clicking techniques. CPS is just for fun — it doesn’t indicate a fault.

Frequently asked questions

What threshold should I use for double-click detection?

The default 80 ms works for most people. If you double-click very fast on purpose, lower it to 60 ms; to be more sensitive to chatter, raise it to 100 ms.

Why don’t my side buttons light up?

Some mice send side buttons as keyboard shortcuts through their own software, which browsers don’t see as mouse buttons. Check the mouse software’s button assignments.

Will right-clicking or Back buttons do anything to the page?

Inside the test area, the context menu and Back/Forward navigation are blocked so you can test those buttons safely.

Does it work with touchpads?

Yes for clicks and two-finger scrolling. Polling rate is meant for mice and may not be meaningful for touchpads.
