Openfire with Jwchat - Single Invocation

We are able integrate the Openfire with Jwchat successfully within our website. Now when the user authenticate via login in our websites, he can invoke the Jwchat initial Window having list of all users multiple times. Now we need that each user should able to invoke Jwchat only once… If he kills the Jwchat window then he can invoke it back … but it should be only one window. I mean Initial Jwchat window having all user list should be only one window. From the initial Jwchat window, he can initiate chat with as many users as possible. Please can some one help me on this.

It looks like a jwchat issue to me, so maybe you should tal to jwchat developers.
