FB.ui draggable IE9

Hi,

I'm using drag&drop jquery features.

What I'm trying to do is to move an image over an other.

Everything work fine on FF and Chrome. On IE9 it doesn't work and I'm not able to fix the problem.

You may found the page on seven.tellnet.it/serven/index_bug.php

To test use the following procedure:

1. click on one of 3 images on the left;

2. try to move the image that appears on the right over the swimming girl

Thanks in advance for your help,

Daniela
