FAQ
Common questions and answers about this topic.
Why isn't the middle or right button detected?
The middle button can trigger the browser's auto-scroll and the right button opens the context menu. Inside the test area this tool suppresses those default behaviors so the clicks register, but it does so only within the area — the rest of the page keeps its normal right-click menu and scrolling. Make sure you click inside the test area.
How do I tell if my mouse is double-clicking on its own (chatter)?
Single-click a button several times and watch the "Double-click interval" reading. If a single physical click produces two events with an extremely short gap (under 50ms), the tool marks it as "suspected chatter" — a common sign of a worn micro-switch. This threshold has no industry standard, so treat the result as a reference rather than a verdict.
Can I use this on a phone or tablet?
This tool needs a physical pointing device (mouse or trackpad). On a pure touchscreen with no mouse attached, there are no left / middle / right buttons or a scroll wheel to test, so the tool shows a notice instead. A laptop trackpad, or a touchscreen device with a mouse plugged in, works fine.
Will my clicks or movements be uploaded?
No. All detection happens entirely in your browser — nothing is uploaded to a server and no data is written to any database. Counts, intervals and the cursor trail live only in the page and are cleared when you reset or leave.
