Hi, Carl, thanks you for the quick response.
It does seem nicer. However, there is still slightly shaking effect during the transition, couple of times for each repetition. I don't know if you can see that. You probably need to watch closely in order to see the shaking issue. Is there anything we can do about that? I tested it in Chrome,FF and IE, the shaking issue only occurs in Chrome and FF, not in IE. In other words, the animation in IE is perfect. (finally something better, :)hehe)
