I use QuickKey, my own script, quite a lot, but I've noticed that after a while, the contact list isn't right.  It's still showing contacts as online, even if they signed out or changed status, and it doesn't reflect any new people coming online.

I made a new script and tried enumerating Messenger.MyContacts, and printing it to the debug with statuses, but the same thing happens.  Is this a bug; can anyone reproduce this?
