Falling Snow updated for AS2 or higher than Flash 6?

Does anyone know of an updated version of falling snow 2 (with mouse directional movement).

The original was written in AS1 and Flash Player 6.

The settings can be updated to work with AS2 but no higher than Flash Player 6. I’ve tried 10 down through 7 various ways.

The only code that seems to cause the slow down is this:

snowflaskes = 75;
duplicateMovieClip(snow, "snow"+k,k);
}while(k != snowflakes);

Has the code changed for the duplicateMovieClip ‘while’ section in later versions?
