In this movie, the SWF is loaded and nothing else happens. This
FLA for this SWF is very simple. There is one timeline, with two
frames. An empty movie clip is on both frames. To create an empty
movie clip, view the Library (CTRL-L if it is not currently visible).
On the upper right of the window, select "Options" and "New Symbol".
Give it whatever name you wish, and be sure to select "Movie Clip"
under behavior. Do not do anything else with this movie clip.
Then, return to your main timeline (CTRL-E if it is not currently
visible) and drag the new movie clip from the library onto your
stage (see "Positioning" above for proper placement of your movie
clip). Now you need to name this instance of your movie clip. Make
sure the movie clip is still selected, view the Instance Properties
panel (CTRL-I if it is not currently visible) and enter a name.
I have used "empty" for simplicity.
In the first frame, there is a Load Movie command. To
do this, select the frame in the timeline, and then view the Actions
window (Window -> Actions, or CTRL-ALT-A). Then, under basic actions
select Load Movie. At the bottom of the actions panel, enter the
URL you wish to load, and the target (in this case, the movie clip
"empty").
Then, the second frame contains a stop command. Please note that
the stop command can not immediately follow the Load Movie command
on the same frame, because such code would fail to load the external
SWF. In this movie, the SWF is loaded and nothing else happens.
