title: Strange Issue in Internet Explorer using Flex
body: <p>Im using a flex plugin with a methode:</p>
  
  <pre><code>ExternalInterface.call("initialize_width");
  </code></pre>
  
  <p>This calls a jQuery Function witch initializes the width of the window:</p>
  
  <pre><code>function initialize_width(){
     $("#nav_content").css("width",900);
  }
  </code></pre>
  
  <p>It works perfectly on all the browsers expect Internet Explorer...</p>
  
  <p>It says: "'null' is null or not an object", and points to:</p>
  
  <pre><code>try { document.getElementById("").SetReturnValue(__flash__toXML(initialize_width()) ); }
  catch (e) { document.getElementById("").SetReturnValue("&lt;undefined/&gt;"); }
  </code></pre>
  
  <p>I've no idea what the problem should be as the place where the debugger points to is pointing to automatically created code..</p>
  
  <p>Any help?
  Thanks Markus</p>
