Without any changes to preferences, IM chats stopped showing up in the local chat console. Notices, Group Chat, green text, etc. all still show up, but personal IMs do not. I have checked the preference settings and they are set to show IMs in chat console. I know when the local chat window is open, they won't show up. This is when the chat window is closed. It was working up until a couple weeks ago and had just stopped. I see this problem has been reported before, and several of my friends on SL seem to be experiencing the same thing on singularity. It is not region specific either, it is everywhere in SL now.
