Having a bit of trouble here, I need a 7x11 square to be repeated 142 across and 64 down. My script is:

Actionscript:

gridx=7;
gridy=11;
num=1;
// Var J should be 64, i should be 142
        for (var j=0;j < 64;j++)
        {
    for (var i=0;i < 142;i++)
    {
    dot.duplicateMovieClip("dot"+num,num);
    mc=this["dot"+num];
    mc._x=gridx*i;
    mc._y=gridy*j;
    num++;
  }
}
dot._visible=0;

And it all works as it should, HOWEVER 142x64 is 9088 and it takes forever to load and I get the 'Script is taking forever to load - do you want to Abort' message. How could I possibly speed it up? Sorry if I haven't given enough info, first time posting but will be happy to add anymore detail if needed.
