Orion version 8.1. I have a lot of alerts configured and enabled. If I open System Manager and click on the blue "Alerts" triangle, I see the "disable alerts" box unchecked as usual. Then I click on the X to close Alerts. If I then click again on the blue "Alerts" triangle, I get NetPerfMon Run-time error 0 and System Manager closes. If I re-open System Manager and go in and check the box to temporarily disable alerts, then close the alerts box, then click on the Blue triangle again I get "Run-time error 381, Invalid property array index" and System manager closes. If no one else has this happen, I will have to open a ticket, I guess. -Debbi
