Display Columns - Select or deselect columns to control the information that displays on the User List window. The window defaults to show list name, level, whether or not the list is a security list (Yes/No) ), the type (global or personal), and the mode (static or dynamic), and the last used date.

OK - Clicking OK applies the changes for the current session only in the User List and User List Maintenance windows. If you navigate away from the windows, display columns return to their defaults.
