Comment 30 for bug 37330

miguelrojas, you are wrong. with openJDK it's possible to close the chat window, but this will not close the active chat session. Your chat partner is not able to see, that you left the private chat.

Most websites, which provide chat rooms based on volano chat software, give a limit in privat chats you can participate at the same time. during the fact, that you cannot close the chat sessions, you will reach sometime the limit. As a consequence you are not able to start more private chats, because the software assumes you already talking to "n" persons.

To conclude this, with OpenJDK it is only possible to "hide" the chat windows.
