I tried this reinstall/repair option, with absolutely no change. The application always loads with "Not Responding", then hangs until the script error times out, then loads when the script error, and the question, "Do you want to continue running scripts on this page?" is answered.
There is an error in the script used to display Alert Notification icons and to display the "How Do I...." help dialogue, and I don't think it's an application error or a corrupted/missing file. The BackupExec_EN.dll is shown as the source of the script error... is there a way to obtain a corrected version of just this one library?
This is becoming a real nuisance, esp. if troubleshooting failed backup jobs/devices, and I can't help but wonder what else is not working correctly, or not being reported accurately by the application?
