I've had the strangest experience. I created a number of nested sequences in my project. These sequences included a video track, a dialogue track and a music track. I played through these nested sequences and everything seemed good to go. I saved the project and quit out of PremPro. Today when I opened up one of the nested sequences the music track has been somehow partially "switched" with another sequence's dialogue track. The music is no longer on that track! (I am working on a mac os, snow leaopard with CS5.5). what did I do wrong?
