The following are the possible reasons for double-clicking with a mouse click:
1. The sensor inside the micro switch under the mouse button is out of order. If the mouse is clicked for a long time, the sensor inside the micro switch under the button will fail, and the click will be misjudged as a double click. This situation generally occurs on the left button, because the left button is used much more frequently than the right button and the middle Xiao key.
In this case, it is recommended to replace the microswitch.
2. The click of the mouse is set to run with one click. If the mouse is set to run on a single machine, it will cause the mouse to be double-clicked once, which can be solved by modifying the mouse settings.
3. The contacts of the mouse button are in continuous contact. The contact of the mouse buttons will cause the mouse to not function properly, in which case it is recommended to replace the mouse.
