This program is indeed very easy to use and the cross-platform feature is
rare and wonderful. Unfortunately, the developers have overlooked one
element which I find is beyond irritating. Since each screensaver uses Quicktime - the computer does not go to sleep regardless of system settings. Any screensaver simply runs and runs and runs until the user interacts. I like the "normal" Mac OS X screensavers because after the set time period they sleep and my system can "rest". So I will buy this when they
figure out how to build in a sleep feature like every normal screensaver.
