title: CSS Filter is stopped by background
body: <p>OK let's say I have this</p>
  
  <pre><code>.test {
  filter:DropShadow(Color=#000000, OffX=1, OffY=1);
  }
  </code></pre>
  
  <p>Yes, it works fine. The text-shadow appears in Internet Explorer. However... if I add a background for color like so:</p>
  
  <pre><code>    .test {
      filter:DropShadow(Color=#000000, OffX=1, OffY=1);
      background:#ffffff;
  }
  </code></pre>
  
  <p>Can you guess what happens? The filter goes way! However, if I ,once again, remove the background property... the filter (text-shadow) comes back!</p>
  
  <p>Help?</p>
