I'm using this on an hover image :

    $('.img-style').hover (function(e) {
    var prixPlus = $(this).closest('a').attr('data-prix'); 
    prixPlus = parseFloat(prixPlus);
    var prixNew = prix + prixPlus;
    $('#chgePrix').html(prixNew.toFixed(2));
    $('#txtapart').fadeTo('fast', 0.1);
}, function(e) {
    $('#chgePrix').html(prix.toFixed(2));
    $('#txtapart').fadeTo('fast', 1);
});

But if I pass quickly the mouse 2 or more times over the image, $('#txtapart') fade in and out 2 or more times ! How can I stop the fade propagation ?

Thanks for your help...
