Chat Lights Up - Nothing There

Chat Lights Up - Nothing There

I submittred a couple help requests a few days ago.  Though I haven't gotten replies yet, I see that, for the first time, my chat sign is lighting up in red in the lower left hand corner.  It also includes the number "1."  But then, when I open up the chat window, nothing happens.  Nobody's there.

Correlating the two events, I wonder if somebody is trying to respond to my help requests by chat?   In any case, now I have a third request...
