Vender control panel error in product list.

Hi,

I have created a menu item of the type Vendor Control Panel. Looks great. However, when I then in the frontend go to "Orders" - choose an order and click on one of the two icons for Product List, the whole web site is just opened again in the popup instead of the product list for the current order.

What can be wrong?

Thanks,

Claus.

Edit: The above error applies to Google Chrome - IE and Firefox just view an empty white popup.

-- url of the page with the problem -- : naestved-cykel-motion.dk
-- HikaShop version -- : Latest
-- Hikamarket version --: Latest
-- Joomla version -- : 3.3.0
-- PHP version -- : 5.3.28
-- Browser(s) name and version -- : Any

Changing the popup mode to mootools in the Hikashop configuration have solved the issue
