What is your mouse doing?
Before replacing your mouse
Repeat, compare, isolate
- 1. Repeat the same test. Look for a pattern, not a single event.
- 2. Try another browser or USB port. This helps separate browser and connection behavior.
- 3. Compare another mouse. A known-good device provides useful context.

Frequently asked questions
Which mouse test should I start with?
Choose the symptom closest to what you notice. Use the scroll test for wheel jumps, the double-click test for unintended second clicks, and the button test for a button that seems unresponsive.
Can one test confirm my whole mouse is healthy?
No. These tests observe specific browser events. Run all three and repeat any unexpected result, but remember that software, operating-system settings, and browser behavior also affect events.
