Interesting... I am working in this area.. and was surprised that JSObject
worked as well as it does in IE given that it is a netscape package..
It seems to be giving a security violation.. possibly because realplayer
comes from a different domain?? ..or maybe just their bug..
Could test (maybe) by relaxing security.. but it probably won't help.
Seems you could get around it by simply calling a javascript function from
your applet.. and have it call the real function..
Also.. what is the bridge you talked about.. I missed it ;-( ..maybe that
is what I just described??
