I use an xbox 360 gamepad for L4D2. However, it does not map all the buttons or let me use my keyboard simultaneously. Therefore, when using a gamepad I lose the ability to vote in game and I lose some other features as well. I can go into options and map voting back to the default F1 and F2, and this works even while using an xbox controller, but it does not save these settings. So when I quit l4d2 and start it up again, I have to map the controls again. Any fixes/mods that help with this?
