When I try to alter the settings for my F keys, as set by default, I only ADD to the key mapping, as its not replacing the previous keymap. This is annoying, because I need to use my F keys combined with Fn, to alter monitor brightness, volume, key lighting, mute etc etc. Atm, the game does reloads, screenshots, Medieval Shell, calling diplomatic meetings etc which is hugely annoying for gameplay. Any solution to this?
