title: How can I hide the cursor in transparent WPF window?
body: <p>How can I hide the cursor in a WPF window that is fully transparent (alpha=0).</p>
  
  <p>I tried the usual </p>
  
  <p>this.Cursor = System.Windows.Input.Cursors.None;</p>
  
  <p>and it works on areas with content where alpha > 0 but when the cursor moves to an area - in the same window - where the background is fully transparent the cursor re-appears.</p>
  
  <p>I also added
  System.Windows.Input.Mouse.OverrideCursor = System.Windows.Input.Cursors.None;
  but that didn't help.</p>
  
  <p>I realize that setting the alpha of background to 1 might be a solution but for various reasons this creates other problems...</p>
