I was wondering , I don't know too much about Flash
I remember seeing some classes in amongst the Flash
files when it installed , but couldn't tell you whart they
do (at the moment , but you've got me interested)
maybe you should rethink your strategy for building your page (and your movie) maybe build the movie around
your applet , or preload it then replace a an area of your movie area with your applet (the way you handle rollovers).
the advantage is you can make calls to applet methods
from Flash as it supports Javascript.
jus remember to set the scriptable <PARAM> to true
Users shouldn't have to download the plug-in or JRE
you should specify it in the OBJECT or EMBED tag so
if they don't have it , the browser will tell them.
of course this is going to change as Microsoft are stopping support for JAVA , users will then have to download the plug-in from Sun in order to view or use JAVA on the internet.
