title: Flash input text field only accepts characters already used somewhere on the stage. What's happening?
body: <p>On the stage I have an input field (classic text, input text) with **no filters** and **no restrictions** and yet, when I try to type something in it, I can only use characters that are already on the stage somwhere else.</p>
  
  <p>For example, I have a few other labels on the stage with the strings '125' and 'HB'. In my input field I can now type any string containing those characters, like 'H52B' or '121212', but I just can't use any other characters! If I press '4' or 'K' on my keyboard, nothing happens!</p>
  
  <p>I am sure there is nothing happening to this input field in actionscript and there are no filters on it. This problem may have something to do with the fact that I got this fla from a designer and upon opening it, I got a message saying something about fonts not being on my machine and converting to system defaults. Could it have something to do with that?</p>
  
  <p>I'm using flash cs5.5 and actionscript 3.</p>
