How to Fix a Mouse That Double-Clicks

Test the Button First

A browser sees a double click as two full clicks on the same spot in a short time, each a press and a release. A worn switch makes the same pattern from one press, because its contacts bounce.

Open the mouse test and click the left button 20 or 30 times at a normal pace. It flags any second press that arrives within 80 ms of a release, and you can change that threshold.

• Faults on one button only: that switch is the likely cause.
• Faults on every button: look at settings, the port, and the computer first.
• No faults here but double clicks in one app: check that app's settings.

Check the Windows Folder Setting

If the mouse has double-clicked since the first day, Logitech points to a Windows setting first. "Single-click to open an item" makes one click act like a double click in File Explorer.

1. Search Windows for "single-click" and open "Specify single- or double-click to open".
2. On the General tab, choose "Double-click to open an item (single-click to select)".
3. Select OK, then test the button again.

Also check the maker's mouse software, such as Logi Options+ or G HUB. A button set to send a double click will do it on every press.

Set the Double-Click Speed

The double-click speed decides how close together two clicks must be to count as one double click. It changes how your system reads clicks, not how the switch behaves.

• Windows 11: Start > Settings > Bluetooth & devices > Mouse, then Additional mouse settings. On the Buttons tab, move the Double-click speed slider.
• Windows 10: Start > Settings > Devices > Mouse, then Additional mouse options, and the same slider on the Buttons tab.
• Mac: Apple menu > System Settings > Accessibility > Pointer Control, then drag the Double-click speed slider.

Clean the Button and Check the Connection

1. Blow compressed air around the button, or use a soft brush, to clear dust.
2. Plug the cable or wireless receiver straight into a USB port on the computer, not a hub, extender, or switch. Try another port too.
3. On a wireless mouse, replace the batteries, then disconnect and reconnect or re-pair it.
4. Update the mouse firmware with the maker's software.

Then run the mouse test again with the same number of clicks.

Try Another Computer

Test the mouse on a second computer. If it double-clicks there too, the fault is in the mouse. If it doesn't, look at the first computer: its settings, its mouse driver, and any app that changes button behavior.

When the Switch Is Worn

Logitech says persistent double-clicking may signal worn switches. If the fault stays after cleaning and on other computers, the mouse needs a repair or a replacement.

Check the warranty before anything else, and contact the maker's support with the steps you've already tried. Opening the mouse to replace a switch yourself may void the warranty.

To check every button and the scroll wheel on a new or repaired mouse, use the mouse test.
