I have met with following difficulties:

1. When I try to kick authenticated user from the chat room I get 'The specified user is currently offline or does not exist.' message instead of banning that user.

2. When I open moderate chat mode and other user sends messages in the chat, I don't see this messages in the Moderator message queue window on the administrator side until I reload the page.

Please help me with this issues.

I'm still waiting for your answer...

Any solution to this issue? Or has someone able to build a workaround for this?
