The index of this book quickly became my best friend. Calling it a "Classroom in a Book" is quite effective, as it will literally teach you a class worth of Flash knowledge through simple exercises.
However, I bought the book as a reference tool for the newer functions of CS4 and for the tools I had little experience with. The book covers almost every imaginable aspect of the software and I recommend it for beginners and seasoned Flash users upgrading to CS4 for the first time.
