Soft Shadows are hard...

I make a spotlight, I set the shadows to soft, I am using unity pro. Yet… the shadows are just as hard as if I had simply left them set to hard… why is this? There doesn’t appear to be any sort of “softness” control on the spotlight…

isn’t a bug, also if i set a spotlight to soft shadows, the shadows are soft, the aren’t really soft, but they are soft.
