Following WPA / WPA2 authenticated failure, scu_tray will pop up a message indicating authentication failure. How do I enable/disable this feature?

You can modify this feature by creating a new registry called ?NotifyAttempts? under ?hklm/software/Laird/ScuTray?, this allows you to disable / enable the pop-up message for WPA / WPA2 authentication and even set the number of attempts before notification. -DWORD: NotifyAttempts -Values: 0 (disabled); NOT 0 (the number of attempts before notification)
