Lets you create 2 hotspots on your desktop, one to turn your screen saver on, and the other to turn it off. You will see a little flag pop up when your screensaver is disabled. As long as the cursor is parked in the appropriate corner, your screensaver cannot come on. This can be quite useful when downloading a large file or doing a tape backup. Having a screensaver come on during either of these activities can wreck havoc with your computer and your files. As well, you can set up a corner to start your screensaver.
