Touchpad Button Malfunction

The left button on my touchpad developed a hard to describe malfunction. Turning on right-handed mode improved the functionality, but accidentally clicking the left button creates a complicated, frustrating situated which can usually only be resolved by restarting. Is there something in the settings or the registry which can disable the button until I get it fixed?

I found an alternative answer. At Walgreens, I saw that mice were marked down from $11 to $6 and I bought the last one. It works surprisingly well for a $6 Walgreens mouse. I'm still curious about my initial question, although it's no longer urgent.
