Mouse double clicking when you click once

Start here: count the clicks

Two very different problems look the same: the computer may treat one click as a double click, or the mouse may really send two clicks. Our mouse test shows which one you have.

Open it and click the left button slowly, one click at a time, for about a minute.

• “Extra clicks” stays at 0: the mouse sends one click per press. A setting is the cause. Start with fix 1.
• “Extra clicks” keeps going up: the mouse is sending a second click by itself. Go to fix 4.
• The problem is on another button: the test counts every button separately, so you can check right, middle, back and forward the same way.

1. Turn off single-click to open (Windows)

Windows can open files and folders with one click instead of two. When it is set this way, everything opens on the first click and it feels like a double click. Logitech points to this setting first when a mouse has double clicked since the day you got it.

1. Open File Explorer.
2. Select See more (the three dots) on the toolbar, then Options.
3. On the General tab, under Click items as follows, choose Double-click to open an item (single-click to select).
4. Select OK.

2. Check the double-click speed

The double-click speed decides how far apart two clicks can be and still count as one double click. If it is set very slow, two separate clicks a moment apart get treated as a double click.

Windows 11

1. Go to Start > Settings > Bluetooth & devices > Mouse.
2. Select Additional mouse settings.
3. On the Buttons tab, move the Double-click speed slider toward fast.
4. Select OK.

Mac: the same setting is Double-click speed under Apple menu > System Settings > Accessibility > Pointer Control.

While you’re on the Buttons tab in Windows, check Turn on ClickLock. ClickLock lets you drag items without holding the button down. If items keep dragging after you let go, turn it off.

3. Check your mouse software

Software from your mouse maker can change what each button does, including setting a single click to send a double click. Open the app that came with your mouse, such as Logitech Options or G HUB, and check that the button you’re having trouble with is set to a normal click.

4. Clean the button and check the connection

If the mouse test shows extra clicks, the second click comes from the mouse or its connection.

1. Blow compressed air around the button and into the gap under it, then test again.
2. Plug the mouse or its wireless receiver straight into the computer, not into a hub, extender or switch.
3. On Windows, try a different USB port.
4. For a wireless mouse, replace or charge the battery.

5. Find out if it follows the mouse

Connect the mouse to another computer and run the mouse test there.

• Extra clicks on the other computer too: the switch inside the mouse is the cause. If the problem stays with the same button, Logitech treats it as a hardware fault.
• Works fine on the other computer: the problem is on your first computer, for example its USB driver or a setting from fix 1 to 3.

A worn switch can’t be fixed with settings. If the mouse is still under warranty, contact the maker. The mouse test shows the gap between the two clicks in milliseconds, and a note of that number and the button helps with a claim.

Check that it worked

Click slowly in the mouse test again for a minute. If Extra clicks stays at 0 and folders open only on a real double click, the problem is solved. If it comes back later, run the test again before changing any settings.
