Overview

This script prevents screen saver from locking down Windows by randomly moving mouse pointer a bit every 4 minutes or so. Why would you need this? Well, if your XP box is in a domain with security-crazy admins who have immutable policy of forced screen saver after 5 minutes of inactivity you’d feel the pain…
