PROBLEM
If user authentication for acess to ArcIMS services works with other ArcIMS clients (ArcExplorer, HTML Viewer, etc) but not the Java Custom Viewer, a bug with the Java Plug-in may be to blame.
In encountering this bug, the user is initially prompted for a user name and password and then, shortly after the input, the browser stops responding to requests and the screen will not update.
The 1.3.1_02 Java Plug-in does not work with Web site authentication for ArcIMS 3.1.
