Miscellaneous: issue sending tells

[Barnes]

This one is very strange, I have been trying to send tells to a guy in the same zone as me so I know he is online, but when I do it says he is not online. So I asked him to send a tell to me in /ooc (I use tell windows) I received his tell but it said to him that I was not online and when I tried to send a reply it said he was not online, even though I was using the tell window he sent me ! so strange. Anyone had this issue?

Oh and I have tried alts and even different accounts and same issue. seems to be only with this one guy so far though lol.
