How to test your mouse
- Move the pointer into the test area. Inside it, right clicks, middle clicks and side buttons are captured, so nothing else happens on the page.
- Press each button a few times: left, right, the scroll wheel, and both thumb buttons. Each one turns green on the drawing and in the table when it registers.
- Scroll up and down, and tilt the wheel left and right if your mouse supports it. Watch the “wheel jumps” counter while you scroll steadily in one direction.
- Finally, click the left button normally at least 30 times. If any press is followed by a second one within a few dozen milliseconds, the test flags it as a double click.
Common mouse problems this test finds
Unwanted double clicks. The most common failure. The metal contact inside the switch wears out and “bounces”, so one press is sent as two. Files open when you meant to select them and drag-and-drop lets go by itself.
Dead or intermittent buttons. A button that only works when pressed hard, or not at all, usually has a worn switch or a loose connection.
Jumpy scroll wheel. Dust in the wheel encoder makes the page jump back while you scroll. Short bursts of compressed air often fix it.
Remapped buttons. If a button sends something unexpected, the cause is often your mouse software or a game profile rather than the hardware.
What to do if a button fails
First, try another USB port and another computer to rule out software. If the double click problem follows the mouse, the switch is worn. Many mice are still under warranty — a screenshot of this test is a clear way to show the fault. For a closer look at clicking problems, use the double click test.
