I personally prefer to not use a screen saver per se. I do have it actually set to blank screen if you look at my preferences. It takes 60 minutes before it goes off so that it doesn't decide to bother me while I am working not so hard. This is mainly because I have this crazy notion (True or not I have never proven) that a screen saver simply makes your monitor work harder. Older monitors did have a need for a screen saver to keep from a standing image from burning the screen and leaving an overlying image but newer monitors do not have this problem like the olds do, but I figure nothing is better than too much.
Rather off topic, but...
Webshots is one of the worse programs to download anymore. The new versions download with so much tracker infested spyware it is unbelievable. I hate this program passionately. Years ago it was not this way and have used it in the past myself but, I would not dare download any of the newer versions. It has also become so much of a resource hog for what it is there for. It runs constantly even when the screen saver is not being used, and anytime that you are online it has a tendency to attempt and download all these new preview images causing slower connection to the internet to get even worse. Sorry about that, just had to rant a little. Glad everyone does enjoy the service though.
