Hi all,

I have a difficult problem that I can see no way to solve. Perhaps someone here can help me?

I’ve been making a flash animation for a client - the dimensions of the stage are 2,000px wide, 800px tall. They want a graphic in the background and a snow effect in the foreground.

The code I have written uses [TweenMax](http://www.greensock.com/tweenmax/) to move a snowflake that has been dynamically loaded from the library on to the stage using attachMovie. When the clip leaves the stage, it is deleted and a new clip is created at the top of the stage.

I expect flash to redraw the background that the flakes pass over, but flash seems to also be redrawing space _between_ the flakes - as if they were one movieclip - even though they are separate instances.

Help! The large redraw regions are killing slower PC’s!
