title: Mouse Move not trigger outside WPF Main Window
body: <p>I want to get mouse position relative to screen coordinates. I am using the following code to do that.</p>
  
  <pre><code>window.PointToScreen(Mouse.GetPosition(window));
  </code></pre>
  
  <p>It is working as expected. But my MouseMove event not firing outside the MainWindow. That is if I move my mouse over desktop with my window restored.</p>
  
  <p>Any ideas appreciated.</p>
