Display Control Not Working in Vista.

[romaelz]

Hi,
I've AR21M. I have installed Windows Vista and to make full use of it i also downloaded drivers for Vista, provided by Sony including the Vaio Update 3.
Unfortunately the Screen Brightness controls on the laptop does not work properly. The brightness bar only goes one step up and only comes one step down, no mater how many times i press the combination of Fn+F5 or Fn+F6. It only works one step up or one step down.
Is someone else having the same problem and has someone got any solution for this.
At the moment i only control the display by going into the control pannel and controling it over there but i wonder why the controls on the keyboard doesn't work.
Anybody knows? Pleae write....
Thanks!!!
