Hi! i have one of the aluminum macbooks running snow leopard on wifi connections. When i try to video chat on ichat with a friend in iraq (i'm in the U.S), the chat will only work if i send the invitation and for a few moments before ichat quits unexpectedly. He is using AIM windows vista. The internet connection is usually pretty good on both ends, and i don't think its a compatibility problem between the two operating systems because i have had video chats with vista users before. any ideas or suggestions that could help me out? thanks!
