I'm looking for a good book on flash/actionscript (MX) for web design. I'm interested in learning more about dynamically creating everything in a site--buttons and content, etc., making everything easily update-able and I'm interested in organizing and optimizing my content for fast execution over the web. I've had problems, for example, with having animated transitions between sections be very slow and laggy because I'm not sure how to code it effectively. I'm also interested in learning about arrays and some practical applications and basically an overall expansion of my actionscripting knowledge. I'm a very impatient reader but I love it at the same time--I like tutorials and things like that. So if anyone can recommend a good book for any/all of this I would really appreciate it, thanks!
