With the new Msg+ it seems to show that my friends randomly log out, but are still typing, with it showing him offline i couldnt type or finish my message. To ensure it's an msn problem I opened facebook on my browser, and he was online consistently.

Newest msn, and newest Msg+.

Messenger Plus! does not interfere with the protocol so this is a connection issue/Windows Live Messenger not Messenger Plus!. I suggest you try contacting Microsoft there is nothing we can do about it.

I have had this issue but I can confirm it is nothing to do with Plus! (or indeed with WLM) because it also occurs sometimes when using Trillian for Android, which connects to Facebook via Jabber (or whatever the protocol for it is).  Obviously an issue on Facebook's side.
