No Remote Screen Displays in Desktop Central Remote Tool

No Remote Screen Displays in Desktop Central Remote Tool

I am using Desktop Central build no:80029.  I have updated my agents.
 
PROBLEM: When I am using the Remote Control tool, I never see any client desktop image appearing.
 
Everything seems to work properly.  Even no error messages.  This is what I experience when opening Desktop Central in a IE browser.
 
1)  From the Tools tab I select Remote Control
2)  I select the client I want to connect to and click on Connect.
3) I see the Reason to Connect Window indicating the client I selected to connect to.  I input a short phrase and hit the Connect button.
4) The appropriate client gets the Remote Sharing window asking to allow the connection.
5) Yes is chosen to allow the connection.
6) It states that the Desktop Central administrator has joined the client at the specified time.
7) View Desktop is clicked on and Loading appears very quickly, but nothing appears from here.
