I had just finished editing a 12 minute movie.added all the music and dialog and credits and titles when I moved the curser ready to start the Make movie operation and the application hung up "not responding" and nothing would move.I had to do a restart of Studio 10 and guess what ,nothing had been saved of my last two hours of work. This has to be the worst piece of software I have ever used. I wonder if Sony ever reads these Forum notices or is this all just one bad joke.
