Scrollbar et Flash

Salut à tous, voilà j'ai réussi à mettre une scrollbar dans un site tout en flash mais le truc, c'est que je voudrais que la vitesse de défilment soit plus rapide...

Je vous laisse le code :
#initclip
_global.FUISmoothScrollbar = function() {
this.init();
};
FUISmoothScrollbar.prototype = new MovieClip();
Object.registerClass("FUISmoothScrollbar", FUISmoothScrollbar);
FUISmoothScrollbar.prototype.init = function() {
var c = this._parent[this._targetInstanceName];
this.w = Math.round(c._width);
this.h = Math.max(34, Math.round(this._height));
this._xscale = this._yscale=100;
c._y = this._y=Math.round(this._y);
this.x = this._x = Math.round(c._width+c._x);
c._x = Math.ceil(this._x-c._width);
this._height = Math.round(this._height);
var scrollH = (this.h-34)*((this.h-34)/c._height);
var s = this.attachMovie("scroll_asset", "scroll_bar", 1);
this.h<45 ? s.bar._visible=0 : s.bar._visible=1;
s.scrolltrack.useHandCursor = s.bas.useHandCursor=s.haut.useHandCursor=s.bar.useHandCursor=false;
s.scrolltrack._height = this.h-34;
s.bar.centre._height = scrollH-10;
s.bar.bas._y = s.bar.centre._y+s.bar.centre._height;
s.bar.basPos = s.bar.centre._y+s.bar.centre._height;
s.bar.bas._y = s.bar.basPos;
s.bas._y = this.h-17;
var m = this.createEmptyMovieClip("mask", 2);
m.lineStyle(0);
m.moveTo(0, 0);
m.beginFill(0x000000, 0);
m.lineTo(-this.w, 0);
m.lineTo(-this.w, this.h);
m.lineTo(0, this.h);
m.endFill();
c.setMask(m);
this.loadScroll();
};
FUISmoothScrollbar.prototype.loadScroll = function() {

Merci de ton attention,
Je te laisse le lien http://www.issamkrimi.com/indexflash.htm puis cliques sur bienvenue, c'est dans les pages bio et presse...
Le lien n'est pas encore ébruité en fait, je préfère finir avant...

J'ai pas encore essayer de faire ce que tu m'as dis mais ça ne saurai tarder, je te dirai ce qu'il en est...

Merci encore
