FastPath Webchat and OpenFire 3.9.3

I'm running OpenFire 3.9.3 on CentOS 6.5.

java-1.6.0-openjdk

FastPath 4.3.1

FastPath Webchat 4.0.2

You can start the process of initiating a webchat just fine.  The LiveChat window comes up and the user is invited to enter their info.  Click the "Start Chat" and the agent is prompted to accept, but when the agent accepts, nothing further happens. 

The above FastPath and Webchat work fine with OpenFire 3.8.2

Does anyone have any ideas here - other than the obvious use OpenFire 3.8.2?  I haven't been able to find anything in the logs that point to an issue.

Thanks much from Oregon
