title: How do you change text in a textbox AS3?
body: <p>I have a TextField called "textbox". I have this code:</p>
  
  <pre><code>textbox.text = 'hello'; 
  </code></pre>
  
  <p>the code is right but its not changing the text when played. The previous text clears but the new text (<strong>hello</strong>) doesn't appear.
  I'm guessing its something to do with the properties but i just don't know what.</p>
