Mouse Buttons Problem
Have you tried checking for a driver patch for your mouse? Mine also lost its keybinding, but the issue resolved when I updated (Razor Mouse)
I just checked. The drivers are up to date
OK, I just experienced another related problem. When I’m on TS with the Push-to-Talk option this doesn’t work if I’m in the game, when I press the button from inside the game, TS doesn’t recognize it and it won’t activate my microphone, but when I’m outside the game (i.e. on Desktop or on the Browser) this works without problems.
What should I do about it?
