PIANOMANSAM Sorry to hear about your experience. I only have 10.4.5 to work with, so this is untested on 10.3.x Make sure to have dragged the entire folder to Applications and run it out of Applications/Power Check. As far as I know there weren't any major changes in appleScript between 10.3 and 10.4 that would have affected this app. If you were happy with 0.2 and extra customization isn't necessary to you, then stick with 0.2 If you do want to customize it, open the contents of the app and take a look at Contents/Resources/Scripts/main.scpt Here you can change the sound it makes or anything else. Btw, if you want to get ahold of me directly, my email is on my user page here. Thanks and good luck!
