Initial tween a bit choppy

I’ve just completed a flash piece with the help of this forum, I’m very happy with the results.

I’m using tweenlite to zoom in and out a map, I’m not preloading the swf file as its on 54kb.

Everything works great but the very first time you click to zoom the map I don’t get a smooth animation it almost just jumps rather than scales smoothly.

Thereafter its fine.

Is there anyway to prevent this? Is there a way of perhaps doing a false tween or something?

I don’t think a preloader would do anything because it still does this even if I wait a few seconds after its loaded.

Its only a small issue but its annoying me.

Thanks in adv
