We have a GPO in place to start a screensaver and lock the screen after so many minutes of inactivity. Unfortunately, some users have figured out that if they put a weight on the keyboard or mouse button while they're away it will prevent the screensaver from kicking on. Obviously I need to come up with a way to stop this from happening. I'm guessing a can use a GPO to set the FilterKeys option to prevent repeated keystrokes or use a script in the event that a setting in Group Policy doesn't exist for this. However, I don't know if there's anything I can do about the mouse? These people will click the left mouse button and tape it down to hold the button down which prevents the screensaver from starting. Any suggestions?
