I decided to try it pre-10.2 as several reviews have said it's supposed to work...:( It doesn't work on my 533 G4 in 10.1.5...I'm waiting for the next few updates of Jag before upgrading, so I guess I will have to wait to use this saver...love the previews of it though, it looks really unique. Oh, and it didn't just not work, it smacked my computer down pretty bad.
