Diagnose unwanted repeat clicks with a deliberate single-click protocol, separate intentional double-click calibration, all-button mapping, raw browser evidence, and matched local retests.
Make slow, deliberate single presses.
Capturing: Auto detect
Red = at/below suspected-repeat threshold; purple = inside intentional double-click window; green = separated presses.
Logical buttons are never merged before comparison.
| Button | Presses | Candidates | Median interval | Median hold |

Pointer down/up timing and browser dblclick signals stay visible instead of collapsing into one opaque score.
| # | Run ms | Button | Event | Interval | Hold | Classification |

Save only controlled runs you want to compare. History is explicit and capped at 12.
A comparison is labelled compatible only when the principal setup fields match.
Do not use one timing threshold for two different questions. The suspected-repeat threshold is for slow, deliberate single-press testing: if two browser-observed releases of the same button arrive unusually close together, the pair is flagged for retesting. The intentional double-click window is for deliberately produced pairs. WebToolArc keeps those measurements separate and also counts the browser's native dblclick signal independently.
Pointer and mouse events reach the page only after the switch electronics, mouse firmware and debounce logic, wired or wireless transport, operating-system input stack, and browser scheduling. That makes repeated short browser intervals useful evidence for a controlled retest, but it does not let a web page inspect the electrical contacts or certify a hardware fault.
The plot shows where recent same-button intervals fall relative to both thresholds. The event table preserves pointer-down, pointer-up, press duration and classification instead of hiding the underlying observations behind a single green/red verdict. Native browser dblclick is shown as a separate signal because browser gesture recognition is not the same thing as a very short raw interval.
Browser button values are logical mappings and can be remapped by the operating system or device software. Back and Forward buttons may be intercepted for navigation. Touch and pen input are ignored because they do not test a physical mouse switch. When the page loses focus, the current interval chain is reset so a long background gap is not misread as part of the same controlled sequence.
Events are processed locally in the page. Saved history is explicit, browser-local, capped at 12 runs, and can be cleared. JSON and CSV exports happen only when requested. The reproducible settings URL contains protocol and numeric settings only; it deliberately excludes raw events, saved history, and the free-form mouse/profile label.
This studio reports browser-observed mouse behavior. It does not claim raw switch-contact telemetry, firmware-debounce inspection, USB polling-rate measurement, operating-system double-click-setting discovery, model-specific warranty diagnosis, or certainty that a worn switch is the cause. Use repeatable controlled comparisons as evidence, not a single web reading as a verdict.
A short click interval does not guarantee the browser emitted a dblclick event. Track recognized pairs and interval timing together.
Save up to five recent runs in this browser, repeat the same setup, clear the history at any time, and avoid treating browser timing as hardware-latency or medical measurement.
Use the tool above first. These notes explain how to interpret, verify and bound the result without displacing the primary workflow.
A useful double-click diagnosis is based on the time between browser-observed press events, not simply on how many clicks occurred. Very short repeated intervals during deliberate single presses are more suspicious than an isolated fast click while you are intentionally double-clicking.
Test the left, right, middle, back or forward button separately and keep the same hand position and clicking style for a run. Mixing buttons or changing grip mid-session makes it much harder to tell whether repeated events come from the switch, the browser or your own input pattern.
Do not treat every native dblclick event as proof of a defective mouse. Browsers also recognize intentional human double-clicks. The stronger evidence is an unexpected second press after a single physical action, especially when the same pattern repeats under controlled tests.
Repeat the diagnostic after reconnecting the mouse, changing USB ports or testing another computer when available. If suspicious intervals follow the same physical button across environments, the evidence is stronger than a result from one browser session alone.
This page records events delivered to the browser; it cannot directly inspect switch contacts, firmware debounce or operating-system drivers. Use the exported interval evidence as a reproducible observation, then confirm hardware conclusions with another environment or vendor diagnostic when necessary.
