Mouse Button and Movement Test
Check mouse buttons, wheel, pointer movement, and click response online to help distinguish browser, setting, connection, and hardware problems.
The tester visualizes pointer movement, primary and secondary clicks, auxiliary buttons, and wheel events that the browser receives. Move slowly across the test area, click each button once, and scroll in both directions without using browser navigation shortcuts.
What does this test measure?
The tester visualizes pointer movement, primary and secondary clicks, auxiliary buttons, and wheel events that the browser receives.
Why is this test important?
Check mouse buttons, wheel, pointer movement, and click response online to help distinguish browser, setting, connection, and hardware problems.
How do you run the test?
Move slowly across the test area, click each button once, and scroll in both directions without using browser navigation shortcuts.
How should results be interpreted?
Missing or inconsistent events can result from the page losing focus, button remapping, wireless interference, connection trouble, or hardware wear.
Normal and problematic results
Missing or inconsistent events can result from the page losing focus, button remapping, wireless interference, connection trouble, or hardware wear.
Technical limitations
Browser events cannot measure true sensor DPI, polling rate, switch lifetime, or internal electronic condition with laboratory accuracy.
Why can the score decrease?
Unstable measurements, denied permissions, unsupported browser APIs, background load, power saving, or an incomplete test can affect the result. When a score changes, the result screen explains the reason.
What should you do if a problem is found?
Clean the sensor surface, check batteries and receiver placement, review button mapping, try another port, and compare another device.

Frequently Asked Questions
How do I tell whether my mouse is double-clicking on its own?
Click once, slowly and deliberately, and watch the counter. If a single press registers twice, the switch is bouncing. This is a common wear fault in older mice and is a hardware problem rather than a setting.
What is polling rate and does it matter?
Polling rate is how often the mouse reports its position, measured in hertz. A higher rate makes movement feel smoother in fast games but makes no practical difference for everyday work. This page measures the rate your browser actually receives.
Why does my cursor jump or stutter across the screen?
Skipping normally comes from the surface rather than the mouse: glass, high gloss and uniformly patterned desks confuse optical sensors. A plain opaque mat is the quickest test. For wireless mice, low battery and USB interference cause the same symptom.
