Is there a way to remove the feature of the Forward and Back mouse buttons but keep the buttons enabled for e.g push to talk? Because everytime I try to use the button (Mouse Button 3) to talk, it goes back to the previous page if I'm on a browser. I tried disabling the Forward and Back keys but if I do that I also can't use them anymore for e.g push to talk. I hope somebody could help me out with a solution, would be very appreciated!
