I have put Flash MX versions of the files for this article in a zip available at http://www.futuremedia.org.uk/ORA/FMX_files.zip, (350k)and will hopefully add a http://www.futuremedia.org.uk/ORA/F5_files.zip (Flash 5 version) in the next couple of days. I dont intend to do a Flash 4 version :D
Because of requests for Flash MX compatible hack files for the Flash Hacks book, they are now available for download as well as the Flash MX 2004 files. You can download the Flash MX zip (10.4Mb) at http://examples.oreilly.com/flashhks/
This means that the Flash Hacks book now fully supports Flash MX as well as Flash MX 2004.
