[FLSH5] Sliding Menu help

I went through the sliding menu tutorial, and I have it down for the most part, however when the movie first loads, the area with the sliding images does a double take if you will, it begins to scroll to it’s starting position, then jumps back to the initial start point and scrolls back to the starting position again… basically, it performs the initial slide twice. Any suggestions? I could post the file if needed, but maybe someone can help without it. Thanks.

anyone??
