- This is normal and is due to the design of the screen. All you can do
- is adjust the brightness and contrast sliders to reduce the shadows
- as much as possible. I understand that the screen is much improved over
- the PowerBook 140, which I have been told has shadows even through it runs
- only in black and white. When I run my PowerBook 160 in black and white,
- there are no shadows.
