Yeah that can be useful. I am not sure if currently some id may be added to disconnected multiple times. Even it does, this should be not a problme in NetworkClient.handleDisconnections(). I personally prefer to keep existing code unless there is good reason (i.e. performance or functionality) for change. Not sure what others think about this change. - Dong ----------------------------------------------------------- This is an automatically generated e-mail.
