How do I stop camera raw with CS3 opening images with automatic settings?

When I open an image in CS3 camera raw (through bridge) it automatically applies 50% brightness, 25% constrast and 5% fill blacks. Does anyone know how to stop this? I have already tried resetting defaults with cntrl, shft, del.

I do not think that these settings mean anything I just think that it is a point so that you have some adjustments to say contrast in both directions if you think about it zero contrast would look shocking.
Your camera exposures will give you a wide range of contrasts etc but you will still see 25% shown when you open them up in camera raw.
