title: AS3 File upload IOError #2038
body: <p>Hey, I'm having trouble doing a file upload with FileReference.</p>
  
  <p>The upload works ok when running the swf in standalone. It works sending the file to a remote server and to localhost (running the same app). But when the swf is embeded in firefox, chrome or safari, I get the IOError #2038. The strange thing is that it works ok with IE8...
  I've also tried uploading the file from an html form and it works (on every browser).
  A crossdomain.xml is set in place with full access but it never gets called (it shouldn't anyways...)</p>
  
  <p>Any help is much appreciated!</p>
