title: How do I change the background of a Flash document using ActionScript 3.0?
body: <p>Let me preface this question by saying that I am a .NET developer at heart, just helping a friend with a project he is working on.</p>
  
  <p>I have been searching online for something that I think should be pretty simple. Here's what I have:</p>
  
  <ol>
  <li>A standard Flash CS5 document with one layer called background.</li>
  <li>The document is associated with a class called 'Game' which extends MovieClip.</li>
  <li>I am executing some logic in the 'Game' class after calling an 'Initialize' method.</li>
  </ol>
  
  <p>I want to change the background color of the document at runtime to something else (e.g., a different color, a gradient, or a picture). Simple, right? Maybe not. I can't figure it out. Can some .NET-friendly soul kindly explain how to fix this?</p>
