How to test your mouse
- Move the pointer into the blue area.
- Click the left, right and middle (wheel) buttons one by one. Each one turns green on the picture.
- If your mouse has side buttons, press back and forward too. The page will not go back.
- Scroll up and down to check the wheel.
- Click normally for a while and watch the message below the area for double-click problems.
How to spot a double-click problem
When a mouse switch wears out, it can “bounce” and send two clicks for one press. This is called chattering. It can open files by accident, drop items in games, or stop drag-and-drop from working.
A real double click by a person usually has more than 100 ms between clicks. If this test shows two clicks less than 80 ms apart while you only clicked once, the switch is probably faulty. Cleaning, a firmware update or a switch replacement can help, and many mice are covered by warranty.
Other common mouse problems
- Scroll wheel jumps: the page scrolls the wrong way now and then. Dust in the wheel encoder is a common cause.
- Side buttons do nothing: check that they are not remapped in the mouse software.
- Right click opens nothing: some programs disable the context menu. Test here to see if the button itself works.
- Wireless lag: low batteries or a far-away receiver can cause missed clicks.
Frequently asked questions
Can I test the back and forward side buttons?
Yes. Press them inside the blue area. The page blocks their normal back/forward action while you test.
What does “double-click problem” mean?
Your mouse sent two clicks very close together. If you clicked only once, the switch may be worn out (chattering).
Does this work on a laptop touchpad?
Yes. Taps and two-finger clicks are detected as left and right clicks, and two-finger scrolling counts as scrolling.
