I don't know if it is true in 0.92, but in previous versions,
you can not use a provate method to handle an event, so you
should use 'PUBLIC SUB cSocket_Read()' instead...

The ClientHandler object is created fine and the child socket is passed through fine, as I can read parameters such as RemoteHost from the cSocket property of the new ClientHandler object.
