I was offline for some time and when I returned, I found my IM window would not pop up. I tried the chat button on the toolbar, choosing 'IM...' from a drop-down menu on a friend's name, etc... And yes, I did check all of the edges of my window to see if it was off-screen, but I didn't see it there either. Is there a way to reset my IM window to is default state/placement to see if that fixes it?
