Alpha fade Slideshow only working on first page load

Using Flash 8;

I have designed a “Before-and-After” slideshow using Alpha tweens to slowly fade one image into another. The effect works great, however, it seems that the effect only works on the first time the user enters that page.

If the user clicks the “play again” button, I reload the .swf and want the effect the play again, but it just moves from the first to second image, without the alpha effect transition.

Is there some way to “reset” the .swf to replay the alpha tween effect? Does anyone have any ideas why it would have this behavior?

The site and effect are purely actionscript, so I cannot do something like “goToAndPlay(1)” in the last frame, the entire site is only in the first frame.

I can attach code if needed, or a link to the URL.

thanks!! Dave.
