A trackpad sends many wheel events for one gesture. On a touch screen, taps count as left clicks.
How to test a mouse for double-clicks
- Click, double-click, middle-click and scroll inside the big box.
- Watch the faults count. A fault means one button went down twice inside the window.
- Press Reset before each new test. Pick 50, 80 or 120 ms for a stricter or looser check.
Questions
What is a double-click fault?
A worn switch can bounce, so one press registers as two. This page counts a fault when the same button goes down twice within the window you choose, for example 30 ms apart. A deliberate double-click leaves a longer gap between the two presses, so it normally does not trigger one.
Is the window an exact measure?
No. The window is a heuristic. A fast human click can fall inside a short window, and a bounce can fall outside a long one. If faults appear on one button only, and the same test on a second mouse shows none, the first mouse is the likely cause.
Why might the back or forward buttons change the page?
Browsers treat the thumb buttons as back and forward navigation. Inside the pad this page asks the browser not to navigate, but some browsers still do. Outside the pad the buttons always work as navigation.
Does this test record my clicks?
No. Clicks and wheel movement are counted in the page only. Nothing is stored or sent. The one thing remembered is the double-click window you chose.
