A chat room function is to allow access to chat room archives (Unlimited Scroll)
In my testing I can ONLY get this to work when ''new chat message'' is displayed on the TOP of the chat window.
I prefer new message's to displayed at the bottom of the chat window! And with this option turned on we lose the scroll back function.
Tomorrow I will put all settings to default and try to track down the issue !
Feel free to test this for yourself if you might want to help. If not sure what to do , just ask here!
