Hi- I just convinced my mom to get a Macbook. I'm trying to do video with her and its not working. 1. She updated to 10.5.4 2. Not running software firewall, but is behind a wireless Netgear router. 3. I'm only behind a linksys router and added some ports anyway that I found on Google. What happens is that when I invite her to video chat, it immediately says on her screen that I cancelled the invitation. Any help would be appreciated. Thanks.
