Not working in IE7 and IE8

Hello,

first of all thanks for this great module !

But i have a problem : when using it with IE, i get an annoying error (only when calling a node, not with the regular colorbox use).
I get the following message : "Request unsuccessful: Not Found"
When i look at the URL, for firefox i have :
<a href="/colorbox/news/newdocument" class="colorbox-load colorbox-node init-colorbox-load-processed-processed cboxElement colorboxNode-processed">New Document</a>

And with IE i get :
<a href="/colorboxnews/newdocument" class="colorbox-load colorbox-node init-colorbox-load-processed-processed cboxElement colorboxNode-processed">New Document</a>

I generate the links with a view and a Custom text field :
<a class="colorbox-load colorbox-node" href="[url]">[title]</a>

Please some help !!

Thanks
