Archived - Mac OS 9: What's New - Notification Manager Alerts
Mac OS 9.0
Figure 1, Mac OS 9 Notification Manager alert
Wherever you reposition the alert window, that's where it will show up again the next time you get an alert.
Multiple notification windows will not show up at the same time. You have to dismiss the first notification to get the next notification in line. For example, if you disconnect and then reconnect your AppleTalk connection, you will first get an alert that your connection was
disconnected, then once you close that window, you'll get the subsequent notification that it is now available.
