This version has been more stable for me. Seems faster when editing now also. Very nice use of keyboard commands. The only features that Amadeus has that this doesn't that I would like are mp3 support and ability to add markers automatically based on some time interval. As much as I like this app, I feel $25-$35 would be a more appropriate price, but since I like it so much more than the $25 Almadeus, I paid the shareware fee anyway. Along with iTunes, I use SoundStudio to conveniently convert my albums to cd's and my cassette books-on-tape to mp3.
