Why window.opener crashes!!!??? -WTF 2004-03-05 - By Justin Watkins
Back
I've narrowed it down to the camera... But can't explain why (or figure out
a way around this). I've seen it here before, and the answer was always,
clean up your connections. Well, unless I'm just being a complete idiot
that doesn't work for me either.
This happens in IE 6, haven't tested any other versions as doing this is
painful enough.
Here's the code....
onUnload = function () {
vid.attachVideo(null);
vid.clear();
vid.unloadMovie();
vid.removeMovieClip();
this.unloadMovie();
this.removeMovieClip();
myCam = null;
delete myCam;
}
myCam = Camera.get();
vid.attachVideo(myCam);
Simple enough, you can even download the fla

You can see the crash with
http://www.justin-watkins.com/wtf/Launcher.html
Repro steps..
1. Open the Launcher.html link above.
2. Accept camera permission (or deny, doesn't matter crashes for me either
way)
3. Close the popup (Don't close the opener first, that works fine)
4. Try to close the opener
Now you can see that the onUnload function clears out everything, but yet
still a crash on the window.opener. If I'm missing something, PLEASE make
me feel stupid, hanging my head in shame would actually be a better feeling
right now :). BTW, this happens even if you just have Camera.get() in the
code and don't attach the Camera stream to anything. Why isn't there a
clear way to close the connection to the camera?
