Operation aborted in IE 6 or 7

Operation aborted in IE 6 or 7


I programmed a site using a fade effect in the image gallery:
http://www.tween-id.com/develop/pitsou/EinVeredHouse1.shtml
On the FF is works fine but on the IE I sometimes get error -
"operation Aborted"
Can someone help me?
The home page of this site is:
http://www.tween-id.com/develop/pitsou/index.shtml
Go to the "selected projects in the projects menu
you can download the site files here: http://www.tween-id.com/develop/pitzubarak.zip
THANK YOU ALL!!!!!!!!!!!!!!!!!!!
