[sldev] Re:SVC-85 - friends lists not working

[Nicholaz Beresford]

One thing that I observe frequently is that I'm getting
IM's into email while I have been logged in.  Sometimes
even a conversation ends in the middle over IM and I later
found that the other person continued to talk but their
stuff ended up in my email rather than in my window.
