[jQuery] Floating Ad stutters/blinks

[rhamp...@leapfrog.com]

I have an animated flash ad -- 12 frame bouncing ball test @12fps --
that moves across the screen. During the slide the animation becomes
choppy in Safari and the animation doesn't advance past the first
frame until the sliding stops in FireFox. How can I keep the animation
smooth while the div is in motion?

#flashDiv {display:block; position:absolute; margin:0; padding:0;
width:200px; height:200px; top:50px; right:-300px; border:1px solid
blue; background:transparent none; z-index:10;}

<script>
 $(document).ready(function() {
        $("#flashDiv").animate( { right:"200px" }, 2000);
 });
</script>
