help: iBook Screen

Hi,

I made that silly mistake upgrading to 10.2.8 without really thinking about it....doh! Ever since the display on my iBook 500 (dual usb) has been sort of grainy, especially around the dock where there's animation, it's perfectly readable and you wouldn't really notice if it you hadn't used the machine before, but it's really annoying me.

I was just wondering if anyone has seen anything like this? I haven't seen anyone mention it so I don't know if it's the update or just my machine screwing up.

Any ideas?

That'll teach me for not looking before I jump! Oh well....let's just hope the screen doesn't die before I get a chance to re-install
