Recently got a Lenovo ThinkPad S431 and the right click on the top mouse buttons don't seem to work for some reason but the bottom right click does. When I turn it on in the settings it doesn't do anything and when I use the latest driver version on the Lenovo website it causes two finger scrolling to stop working and the top right click button still doesn't work. Does anybody have any ideas on how I can fix this? I've tried uninstalling the drivers and letting windows install it and the drivers on the Lenovo site made it worse. Using windows precision drivers didn't fix it either.
