title: programmatically moving the mouse while the computer is locked
body: <p>I have a program which monitors user's presence by monitoring the mouse movements. I need to make that program think that a user is present at all times. Programmatically moving the mouse every once in a while is very simple. However, I can't make this work when the computer is locked. </p>
  
  <p>I work on Windows XP and have no need for the solution to support Vista or 7.</p>
