Double Click Test
Test your mouse for unintended double clicks — a single press that gets registered as two, often an early sign of a worn or failing mouse switch.
This test can flag suspicious click patterns, but it cannot conclusively diagnose a hardware fault on its own — treat a flagged result as a signal to investigate further, not a certain diagnosis.
How to Use This Test
- Click the box at your normal, everyday pace — single, deliberate clicks.
- Watch the click log: each interval between clicks is shown in milliseconds.
- Clicks registering less than ~45ms apart are flagged as possible "chatter" — faster than an intentional human double-click.
Understanding Your Results
The fastest interval is the shortest gap between two consecutive click registrations. Genuine, deliberate double-clicks from a human are essentially never faster than about 60–80ms; intervals well below that — especially recurring ones — suggest the switch is bouncing and registering one physical press as two electrical signals.
About the Double Click Test
Mechanical mouse switches wear out over time. As the metal contacts inside degrade, a single press can occasionally "bounce" and send two signals instead of one — this is commonly called switch chatter or unintended double-clicking, and it's a frequent cause of accidentally double-clicking files, double-firing in games, or deselecting text you meant to select.
This test can't open your mouse and inspect the switch, but it can show you exactly how your browser is receiving your clicks, which is a solid first diagnostic step.
Tips to Improve
If chatter appears consistently on one specific button, that button's switch is the most likely cause.
Some mice let you adjust a "debounce" delay in manufacturer software, which can mask (but not fix) minor switch chatter.
If chatter is frequent and consistent, the mouse switch may need professional repair or the mouse may need replacing.
Frequently Asked Questions
Two click registrations firing less than about 45 milliseconds apart — far faster than a human can intentionally double-click.
No — it only detects and reports the pattern. Fixing a worn switch typically requires cleaning, adjusting driver-level debounce settings, or replacing the mouse.
A single flag can happen occasionally even on a healthy mouse. Frequent, repeated flags are the stronger signal of an actual hardware issue.
