Why can't I acknowledge alarms from the Global Event Viewer in Vista in StruxureWare Power Monitoring 7.0?

How can we help you today?

From the StruxureWare Power Monitoring 7.0.1 User Guide :
Acknowledging Alarms
The alarm acknowledgement function is now available only in the Alarms application in the Web Applications component. See the online help for the Alarms for information about acknowledging alarms.
Every type of event has a prioritized value that identifies its relative significance on a scale of 0 (zero) to 255. By default, Vista identifies any event with a priority of 128 (default) or greater as an alarm.
