Nicolas,
I understand that this issue relates to the templates way of displaying the default component and not directly linked to HikaShop - however, it seems that lots of users are seeing this 'problem'. Is there no way of bringing the display of this into the components own backend? Even just with a basic styling.
Or, is there another way to show the addresses instead of in a popup? Personally I'd like them to be directly on the page but I seem to remember this was discussed in another post and wasn't a possibility?
