Wireless Mouse

Suddenly the right click of wireless mouse is not working properly. I have to press hard to rightclick.

What could be the prob? I tried with new batteries but the same prob.

The microswitch for the right-click button could be going bad.

Open the mouse and first try to ■■■■ away possible dust. When that does not help spray some contact spray on the switch with the mouse disconnected from the computer and see if that helps or not.
