Running chat on 4.8.  Three of us in the chat.  Chat stopped responding.

Event viewer on the WWW server logged:  ISAPI 'c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'.   Did not see any related errors in the DNN event viewer.

Anyone else having any similar problems? 

Runnin chat on 4.07.  Locked it up with two people on default settings (correction, I've disabled formatting).  Seems like I have to 0 out the history in order to clear the chat screen.  I've been playing with the settings such as History Capacity and Display Capacity to see if there is a problem there.  I've even manage to lock it with both capacities at 10.  The strange thing is that I didn't even type anything, just edited another module on the page, switched between edit and view mode.  The chat screen filled with [joined] messages (more than I would think) and it wouldn't let me add anything to the conversation.  When I say it locks I mean it won't let me add anything to the conversation.

I'm going to keep playing with it.  I like the direction this project is going.  I was very happy to see a core chat module.
