What this mouse test checks
- Left, right and middle buttons – each click is counted.
- Side buttons (back/forward) on gaming and office mice.
- Scroll wheel up and down.
- Double-click fault: if one press registers as two clicks very close together, the tool shows a warning.
The double-click problem
A worn left-click switch can “bounce”, sending two clicks for one press – files open when you only wanted to select them, or drag-and-drop fails. Click slowly ten times: if the warning appears, the switch is likely wearing out. Cleaning sometimes helps; replacing the mouse (or switch) is the permanent fix.
Wireless mouse not responding?
- Replace the battery – low batteries cause lag and missed clicks.
- Plug the USB receiver into a port closer to the mouse (front USB on desktops).
- Re-pair Bluetooth mice in Settings → Bluetooth & devices.

Frequently asked questions
Can I test my laptop touchpad here?
Yes, but the dedicated touchpad test also checks tracking and gestures.
Why doesn't the middle click register?
Some browsers use middle click for auto-scroll; click inside the box to test it.
