title: How do I programmatically remove a mask that was defined in Flash Professional?
body: <p>I realize this is a total newbie question, but it is driving me crazy...</p>
  
  <p>In Flash Professional I have a movie clip, say 1000px high and 50px wide.  I have it contained within (under) a mask layer where the mask is 100px high and 50px wide.  In my program I move the movie clip vertically and as expected it is masked such that I only see 100px vertically.  </p>
  
  <p>My question is: how do I remove the mask from my movie clip?  When I debug inspect the movie clip in Flash Builder, its .mask property is null.  But it <em>is</em> masked... </p>
  
  <p>What am I missing?</p>
  
  <p>Thanks in advance,</p>
