A contentious subject line to grab people's attention!  But first, a
request: part 2 of FadeToBlack 3.2 on comp.binaries.mac didnt reach
this site.  Can someone who has it send it to me please?

Well, do screen-savers like FadeToBlack, Moire, Blackout, Flex, etc. do
anything useful?  They are supposed to prevent the image being
"burnt-in" to the screen by blanking the screen after n minutes of
inactivity.  However, for two or three years I had a Mac+ in my office,
running about 8 hours a day, and although I tried out umpteen
screen-savers, for most of that time I didnt use one.  There was never
any sign of burn-in.  A few weeks ago the + was changed for a II, with a
colour screen.  Are colour screens more susceptible to burn-in?

Moire and Flex do provide pretty patterns, but I generally prefer to be
able to look at my Mac and see what I was doing when I left it.
