While using IRIS, it and third party applications may notify you of events or ask you follow-up questions through the notifications viewer (N). This area is empty when no notifications have been sent. When a notification appears, you can select it at any time and you will be taken the appropriate application to handle or read more about the issue. If the notification is urgent, the Notification title bar will appear red.
Note:
After you select a notification, it is removed from the notification viewer.
Both read and unread notifications are removed after every session.
To clear all notifications, click View->Clear All Notifications in the top menu bar.
