I have an issue with my girlfriend's MSN on her eMac and iBook. With her iBook everything works fine. She can chat away to her hearts content. However, on her eMac is where the problems start. She can see what I, or anyone else, sends her; but no-one can see what she types. I have checked all the Messenger settings, along with the Network and Sharing prefs within System Prefs but still no joy. Any ideas?
