I opened iTunes just now, and for the first time it has a shared bit on the left hand side with katie's music there and I can see all their music and stream it aswell. The only way I can think of this happening was if some one was running off our network as I know it's not secure. We don't know our neibours that well but are preety sure none of them are called katie. So could anyone shed some light on what might be happening?
