I've been using Yahoo Messenger with Snow Leopard just fine for a while, but now all of a sudden the webcam feature does not work. When I try to invite someone to view my webcam they just see a black screen that says "Starting Webcam Session...", but it never loads. Similarly, when I try to view someone's webcam, the same thing happens on my end. Has anyone else encountered this problem? Like I said, it was working fine until a few days ago. Thanks.
