title: Internet Explorer does not unload SWF when navigating away from page
body: <p>I'm writing a conferencing portal using the open-source OpenMeetings, which is a Flash app that is compiled with OpenLaszlo. So, I have access to the SWF source code which is a mix of Laszlo markup and JavaScript, but not ActionScript.</p>
  
  <p>The problem I am having is that when users navigate away from the app in Internet Explorer, their microphone remains connected and they can hear the other party/other party can hear them. This means IE is not properly destroying the Flash object. </p>
  
  <p>I've had trouble reproducing this bug on my own system, but it does occur on my co-workers computer. </p>
  
  <p>I have tried to use JavaScript to capture the unload event and set innerHTML to "", which removes the Flash object from the page, but again, the microphone etc remains connected. </p>
  
  <p>This only happens with Internet Explorer. This is a major bug for our software, as we deal with education and hence a student remaining "on the line" without knowing could open us up to a lawsuit!</p>
