I still have the same issues, app wants to do a force shutdown every time, even with no UPS connected. I also notice now that when it asks for my administration password, the buttons do not work. I either have to enter the password and press the enter/return key or just do the same without entering the password.

Is this app developed for Intel only? I am trying it with a Dual G5, a Cyber Power CP1200AVR UPS and OS 10.5.5
