It is not a secret that Final Cut Studio 3  Applications are not the the most stable of applications. Very often we need to delete the preferences of Motion, Final Cut etc in order to make the applications work the way they should. Saying this I very often delete the preferences of Apple Motion when I see that my performance of Apple Motion is suffering or when Motion starts to crash frequently. Anyway this application can help you do all that in a click of a button.
