I have an old Logitech MouseMan M-RR63 cordless mouse that I use with my PC running Windows 10. I use it left handed and my pinkie finger often accidentally presses the small button on the left side of the mouse. So I want to disable it but I don't know how. I downloaded and installed both Logitech Unifying Software and Setpoint Settings from the Logitech website, but neither of them has the option anywhere to disable that button. Any ideas?
