Recap:


--  Netscape 4 browsers start up faster by not loading Java until they

reach the first Java-savvy page in a session.


--  Because the Flash and Director plugins can use Java via LiveConnect to

communicate with JavaScript, they'll trigger Java loading in that browser,

if it hasn't already loaded in that session.


--  Director has had a "swLiveConnect" EMBED attribute which defaults to

TRUE, and which can be set to FALSE if you do not have any externalEvent or

evalScript or play/pause/goto work in the piece. This means that if Java

has not yet started in a NS4 browser, that the shocked page will not

trigger Java loading.


--  Flash 2 does not have a swLiveConnect EMBED attribute, and so if a NS4

browser starts up and immediately goes to a Flash page, Java will load

before you see the page. (If Java has already been used in that session

then you'll just see the page normally... Java only loads once per

session.)


--  The Flash 3 plugin adds a "swLiveConnect" EMBED attribute, but it

defaults to FALSE. This means that NS4 browsers which have not yet loaded

Java in that session will not load it when they reach a Flash page.

    However, if your page uses FSCommand, or if it has JavaScript send

play/pause/goto messages to the plugin, then you will need to include

"swLiveConnect=TRUE" in your EMBED tag in the HTML.



So, you don't need to include an "swLiveConnect=FALSE" in your EMBED,

because Flash 2 plugins won't recognize it and Flash 3 plugins have that as

the default anyway.


However, if you *are* using FSCommand or JavaScript buttons to control your

Flash movie, then you *will* need to include "swLiveConnect=TRUE" in your

EMBED tag so that the Flash 3 plugins can communicate with the page.


Does this phrasing work for everyone out there...?
