bug plusieurs XML

Bonjour,

J'ai un probleme avec un diaporama en xml (je veux en utiliser un différent pour chacun de mes menus) quand j'ouvre le premier impec mais des que j'ouvre un 2ime les photos défilent trop rapidement (bug) je pense qu'il faudrait que je décharge à chaque fois mon xml mais comment faire ?

ci-dessous mon code :

function loadXML(loaded)
{
    if (loaded)
    {
        xmlNode = this.firstChild;
        image = [];
        caption = [];
        total = xmlNode.childNodes.length;
        for (i = 0; i < total; i++)
        {
            image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
            caption[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
        } // end of for
        firstImage1();
    }
    else
    {
        content = "file not loaded!";
    } // end else if
} // End of the function
function nextImage()
{
    if (p < total - 1)
    {
        ++p;
        if (loaded == filesize)
        {
            picture._alpha = 0;
            picture.loadMovie("photos/" + image[p], 1);
            caption_txt.text = caption[p];
        } // end if
    } // end if
} // End of the function
function nextImage1()
{
    if (p < total - 1)
    {
        ++p;
        if (loaded == filesize)
        {
            picture._alpha = 0;
            picture.loadMovie("photos/" + image[p], 1);
            caption_txt.text = caption[p];
            slideshow();
        } // end if
    } // end if
} // End of the function
function prevImage()
{
    if (p > 0)
    {
        --p;
        picture._alpha = 0;
        picture.loadMovie("photos/" + image[p], 1);
        caption_txt.text = caption[p];
    } // end if
} // End of the function
function firstImage()
{
    if (loaded == filesize)
    {
        picture._alpha = 0;
        picture.loadMovie("photos/" + image[0], 1);
        caption_txt.text = caption[0];
    } // end if
} // End of the function
function firstImage1()
{
    if (loaded == filesize)
    {
        picture._alpha = 0;
        picture.loadMovie("photos/" + image[0], 1);
        caption_txt.text = caption[0];
        slideshow();
    } // end if
} // End of the function
function slideshow()
{
    function pause_slideshow()
    {
        clearInterval(myInterval);
        if (p == total - 1)
        {
            p = 0;
            firstImage1();
        }
        else
        {
            nextImage1();
        } // end else if
    } // End of the function
    myInterval = setInterval(pause_slideshow, 16000);
} // End of the function
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("photos.xml");
listen = new Object();
//listen.onKeyDown = function ()
{
    if (Key.getCode() == 37)
    {
        prevImage();
    }
    else if (Key.getCode() == 39)
    {
        nextImage();
    } // end else if
};
Key.addListener(listen);
previous_btn.onRelease = function ()
{
    prevImage();
};
next_btn.onRelease = function ()
{
    nextImage();
};
p = 0;
this.onEnterFrame = function ()
{
    filesize = picture.getBytesTotal();
    loaded = picture.getBytesLoaded();
    preloader._visible = true;
    if (loaded != filesize)
    {
        preloader.preload_bar._xscale = 100 * loaded / filesize;
    }
    else
    {
        preloader._visible = false;
        if (picture._alpha < 100)
        {
            picture._alpha = picture._alpha + 10;
        } // end if
    } // end else if
};

Merci d'avance
