When logging on to NWBC it could happen that you get a basic authentication logon window with no client field, and when logging on you end up in the wrong client.
(Example)
Make sure that on the Error Pages tab in SICF under Logon Errors the option for Explicit Response Time is not active. Use the System Logon instead.
(SICF example)
