Thanks for starting this thread. I to have had a hard time trying to get the screensaver to activate. It works just fine in the pre-view as well in the full screen test. However, when it some to actually initializing the screensaver fails to run. The screen just goes black. he system comes back to life with a simple mouse movement but it seems that choosing any screensaver just initializes a blank screen effect. Any clue on a fix for this?
