I looked at the book and found it interesting. When I inserted the CD, I realized it was totally user-unfriendly, it was like go figure how we created this $#%*!!! Some of the files don't work at all !!! This CD has been created not to help a user, but to render him confused. I have been using flash for about 5 years and have owned some other books with much better CDs. This is the worst one. What a waste !
