Login Dialog
The login dialog is used to login to a Matrex Server in order to
connect to it.
You need to enter a userid and a password that
are valid for the Matrex Server you are connecting to and click Ok
(pressing cancel stops the connection process).
If the server
was installed without changing its default configuration, a valid user
is guest with password guest.
If the userid does not exist you will get the error The user id ... is not registered in the
server , if the password is wrong you'll get wrong password.
