Yeah, I've seen something similar happen with one of my contacts, who was using Windows Live Messenger (it doesn't happen when he uses aMSN on Ubuntu). I have no clue what was causing it, he wasn't doing it manually either (and, he's smart enough to now have any adware/spyware on his PC

)
Not sure if these are related, but a few other oddities I've encountered:
- I had a conversation open with someone and stopped talking to them... "[name] joins conversation" messages were coming up every single minute. This didn't seem to happen for anyone else (I get the normal "has been closed due to inactivity" message), just this one person. Some sort of keepalive thing maybe? I've no clue.
- Another person I was chatting to, "[name] leaves conversation" kept coming up right after they messaged me, and I'm sure they were not closing the chat window or anything
Any idea what could cause those issues?
