Dear Ralf,

Go into the Settings Manager; open Screensaver; go into the *Advanced* Tab
and make certain that, under Display Power Management, Power Management
Enabled is *unchecked*. Also make sure that Fade to Black when Blanking is
also *unchecked*.

This should fix the problem. Please let me know.
