Crashed constantly when I first used it on my iMac running 10.3. After a while, it refused to load at all. The update only made the problem worse, so I've had virtually no use of it and can't recommend it to anyone. Whatever is wrong with it, the Hemera people should have fixed it, but they haven't and show no interest in doing anything.
