title: Flash failing to fire any Events on URLLoader sometimes
body: <p>I have an instance of URLLoader that works perfectly on my machine and a number of other machines, but in a few rare cases, regardless of the browser or the flash player version, URLLoader never comes back with any of my callbacks and so the load() method is fired off into the stratosphere and nothing happens beyond that.</p>
  
  <p>Curious if anyone else has encountered this and if so how they got around it.</p>
  
  <p>[EDIT]</p>
  
  <p>Ok... never mind on the "no callbacks are fired". In fact it is firing the SecurityError.SECURITY_ERROR.  However, I'm at a total loss as to why it would only fire this on some machines and not on others.  Does it have something to do with the user's admin privileges or the browser's security settings? The error is 2170, phaseTwo (whatever that means)</p>
  
  <p>[EDIT 2]</p>
  
  <p>EUREKA!!! To www or not to www that is the question (or rather the answer).  The issue had nothing to do with computers, but rather with the page being loaded without the www in some instances. Flash doesn't know what to do in that situation. Brilliant! </p>
