Mouse double-clicking and click chatter

One rapid pair of clicks is not a diagnosis. Look for a repeatable pattern from deliberate single presses, then test whether it follows the mouse.

Treat repeat timing as evidence, not a verdict

Open the double-click test and make deliberate single clicks with a relaxed rhythm. BenchRush flags very rapid repeats under its test threshold because they are worth retesting; it does not claim that every rapid interval is electrical switch bounce. Hand movement, an intentional double tap and browser scheduling can all create short intervals.

Use a controlled 20-click run

Rest the mouse on a stable surface.
Use one finger and make clearly separated single clicks.
Do not chase speed; the goal is repeatability.
Repeat the run two or three times.
Write down whether suspicious repeats occur on the same button and at a similar frequency.

A pattern that repeats across controlled runs is more useful than one isolated event.

Separate application settings from device behavior

Operating systems have a double-click speed setting, but that setting usually changes how two clicks are interpreted by applications; it does not repair a switch that physically emits extra transitions. Still, test another browser and another application before blaming hardware. If the symptom exists only in one program, investigate that software first.

Change one hardware layer at a time

Reconnect the mouse, try another USB port or receiver position, and if practical test another computer. For wireless mice, confirm power and connection stability. If deliberate single clicks produce the same rapid duplicates on multiple computers, the case for a device-level problem becomes stronger.

Side buttons and navigation are a special case

Back/Forward buttons can trigger browser navigation instead of behaving like ordinary content clicks. BenchRush captures those buttons on the mouse-test page so you can confirm whether the browser exposes them, but missing side-button behavior can still be browser or driver specific. Use the mouse button & wheel test for that question.

When to stop browser testing

If a repeatable duplicate-click pattern follows the same mouse across browsers and computers, further webpage testing adds little. Check the manufacturer's software, firmware, warranty guidance or repair options. If the pattern disappears outside one browser, focus on that environment instead.

After confirming clean click delivery, the polling-rate estimate can document browser-visible pointer cadence, while the CPS test is a speed challenge. Neither should be used to diagnose switch electronics.
