Use the Look Selections menu to reach panels that display exception messages and the status of exception processes. The list panels display the last 500 exceptions and authorization failures that occurred during your Online Monitor session. When this limit is reached, the oldest entries in the list are discarded as new entries are added. When these windows are first displayed, the bottom of the list is displayed and shows the most recent exceptions that occurred.

The following topics describe the windows that can be accessed from the Look Selections menu.
