Default to "no track"
In your documentation, I find : "playlist.tracks.default (...) If no default is set, captions are not shown on startup". But my experience with JW6 is that, if no default is set, JW6 use the "jwplayer.captionLabel" cookie to set the startup track.
Is there a way to force JW6 to ignore the "jwplayer.captionLabel" cookie and start without any track ? I could manually remove the cookie before launching JW6, but for some reason, it doesn't work.
