I can't speak for color screens, but I always had my doubts about the
burn-in problem as well. That is, until I helped install 40 new Mac Pluses
in the computer center here this summer ("Kiewit Computation Center-- It's
not just a job, it's a bomb shelter.")

They were replacing 512KEs w/ 1 Meg Dove Boards, and most had been 128Ks to
begin with. And yes, many had ghosts of the desktop. This seems to be due to
students just ejecting their disks and walking away; we Student Assistants are
vigilant, but we can't catch everything.So... save your screen!

I have a question of my own: a friend claims the new Moire, which activates
on shutdown now, does not park the heads on his hard drive on the shutdown.
Does it allow the full shutdown procedure to take place? (Is there any way I
can tell if my internal 80 Meg is getting parked?)

And isn't After Dark's "Can of Worms" an attractive screen saver?

Ciao,
Danno
