Using Wildform Flix as external movie in Flash

Hi, here’s the thing - I made the SWF file using Wildform Flix, with options to begin automatic playback when loaded and to unload at end, with player added to it.
Now I’ve added still image in Flash, made it a button, with code to load .SWF movie into level. The problem is that when the Wildform SWF ends, screen is still black with player controls on the bottom. Now can I make the SWF movie unload (dissapear, fade away, forever!) and return to still image?
The idea is to have still image, and when user clicks on it SWF movie is played and it returns to still image. It is very frustating since I think there is simple solution to this that I just can’t see!
I also tried using unloadMovie command, but it didn’t help…
Thanks,
Rudy.
