Loaded SWF on rollover

with Button1, onRollover load movie.swf. this swf is designed to appear exactly where Button1 appears, then move down, and over. The problem when it starts its tween it covers Button1 (forcing a rollout) then moves down (forcing another rollover). When this second rollover begins, it reloads the movie. Causing it to reload over and over until the mouse is moved away from the button. It's quite the inconvience.

Is there some scripting or a way to set a variable so it will ignore all other rollovers until the variable is reset?
