Just cause it is 'real',  doesn't make it necessarily have to be big .. ;o)

For someone who doesn't consider himself to be a programmer, I'd say
you're not doing too badly with your scripting ( what's a programmer
anyway? ) .

Using loadSound, does not *embed* the mp3 audio file in the swf.  It
simply creates a reference to an external file, streamed or otherwise.

Try it this way,

        .action:
               snd = new Sound();
               snd.loadSound("audio_file.mp3",true);
               snd.onLoad = function (){
                      snd.Start();
                                            };
        .end

Bad choice of phrasing and reference, sorry.  Nonetheless, that is
what .stop on it's own appears to do, i.e. kills everything.  You want
to stop  just the snd object itself, then you have to specifically
state it.

Actually no it doesn't.  See below.

It is, but see below.

No bug there.  You've stated  *1 frame per second* in the header,
right?   The sequence only lasts
two frames, so  after two seconds the sequence simply starts again.

Actually, no it doesn't.  Here is an example that shows you all works
aok, and with 'version=10'

Hope that helps.
