Hi, Did this issue occur with USB mouse? Please logon with Clean Boot to see if the same issue occurs. Also make sure the mouse is compatible with Windows 7. And try to reinstall the driver for touching mouse. Perform a whole disk scan to check if any virus in your PC. Furthermore, you can contact the manufacturer to check if the mouse has some issue.
