It may be a feature, but it doesn't work correctly on my forum. It rarely flashes, and when it does, 1/2 the time there are no new chats. I had this problem with the Lite version, and posted about it on vb.org and was told "Nobody else has reported this problem and it's not easy for me to debug as such, I'm afraid." since I liked the chat box and figured maybe it was working in Pro (or maybe I could get better support), I purchased. Well, it's still not working.
