Hi!
I'm sorry, but that is IMHO a Hardware problem. The seti "Screensaver"
is no real Screensaver. The savers were invented to prevent "burn-in".
When a picture is shown on a monitor for long time (for *REALLY* old
monitors hours could be enough, newer should need days) it "burns"
into the screen and is visible permanently - the screen is damaged.
The REAL screensavers activated after a while and showed a changing
image to prevent this "burn-in". Real screensavers don't let any
pixel of the screen unchanged for long. Real screensavers are:
Flying Windows/Toasters
Bezier
Starfield Simulation
etc.
The "3D Labyrinth" screensaver with the map active is NOT a real
screensaver: The "You are here"-arrow in the center of the screen
doesn't move!
The seti Screensaver has also not changing pixels, so you should ust
the CLI or the Windows version WITHOUT the Screensaver! (Set it to run
the calculation permanently and set the windows screensaver to
something like "Bezier") You could also set the SETIsaver to blank the
screen, but this is dangerous: people could think the PC is off and
try to turn it on...

I fear you will need a new screen. (BTW, only CRT's are affected by
this risk)

ya, perm damage from so called screen savers
i only ever ran the seti one when it started for a bit, did it stay on the
same image ya ?
:(
if so, why didn't the designers think about this before hand
personaly i use power saving on my monitor not any screensaver
which is the way it should be really (if a bit boring, it *does* save your
screen)
