So I've been having two big problems with iChat lately. One, when someone tries to initiate a text chat with me, I hear the message recieved sound, but there won't be a window for about 10 seconds, then I get an error message saying I failed to join the chat, but after I hit OK, it opens the chat window. The other is that whenever I send a message, I'll press enter, but right next to my name the bubble will show that I'm typing something for about 5 seconds, then it'll show what I typed. What should I do?
