haiku/src/prefs/screensaver/ScreenSaverWindow.cpp
Michael Phipps 048f424d11 Last round of functionality changes. 
"Add" and "test" now work. Be warned - without the input server addon running (and maybe even with), testing will cause the ScreenSaver to run but not to turn off. The way out of this is to alt-f# to a different workspace and kill "OpenBeOS ScreenSaver".

As far as I know, all functionality now in place and working properly. Needs a good workout.
