Reconnecting moves PMs all the way to the left.

[ghost]

I had some PMs open talking to people, then I closed the window and returned later and all my PMs were moved to the leftmost tabs. I would think that leaving the layout just how I left it would be the desired behavior.

I don't know if this is by design or not, so maybe it's a good thing to have them all move to the left to force me to clean them out when I reconnect, heh.
