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)
