hm, time to clean the computer screen, is it?
I was sitting comfortably, powerbook in my lap, legs on the table, my back to the livingroom window. Problem was, I could hardly see through the dirty screen. Weird how I've negelcted cleaning it as it doesn't take much:
To clean your PowerBook screen, do the following:
Shut down your PowerBook and remove the battery.
Dampen a clean, soft, lint-free cloth or paper with water only and wipe the screen. Do not spray liquid directly on the screen. (from powerbook - care and handling).
Sort of embarrassing thing to share, everybody else probably clean their displays like once every week.
