After buying the Revolution and installing Setpoint 330, my screensaver no longer comes on at all. I disabled setpoint via msconfig, rebooted and it works fine. So I know it's related to your software. Anyone else experience this (or other) issues similar to mine? I've emailed Logitech Tech Support and their only suggestion so far was to uninstall and reinstall the software but that did not help. Also, my monitor is set to turn off after 20 minutes in the Power Options but it never does. Obviously it's related to this setpoint issue but does it mean that something is running in the background and the computer does not know that's it should be idling?
