Fix Mouse Double Clicking
A mouse that double clicks on a single press usually has a worn switch, but settings can mimic the problem. Test it first with the mouse test.
Test it
Click steadily: the tester flags clicks registered within a few milliseconds of each other, which humans cannot produce.
Check settings
On Windows, make sure File Explorer is not set to single-click to open, and check the double-click speed in Mouse settings.
Software debounce
Many gaming mice let you raise the debounce time in their app, which hides switch chatter.
Hardware
Static or dust can cause chatter; unplug for a minute and clean around the button. Persistent chatter means the micro-switch is worn. Check warranty before replacing it.
