Rigs of Rods

I'm using a Logitech G25 wheel.
In the controls you can set a Deadzone up to 30%.
Well it does work, but the deadzone is added on the wrong end of the input scale.
In the test screen, both the 'result' and 'raw input' bar start at the same time when pressing the pedal a bit. With a deadzone of 30%, the 'result' bar will reach the end by 30% earlier than the 'raw input', so the last 30% of the raw input bar have no effect.
This is wrong, the deadzone should be at the start of the 'raw input' bar, so that when you start pressing the pedal, nothing will happen until the bar is 30% filled, THEN the 'result' bar should start.
I'm using Windows Vista, not sure whether it works on Linux or Mac. That's why I set the operating system to Windows for now until some people have confirmed this.
