V4 Javascript popup in Internet explorer


I’m using Javascript popup for some pages and it works fine in Opera, Chrome, Safari.

But Internet Explorer puts the page-string in between the url.

Opera, Chrome, Safari:

http://www.xxxxx.nl/net-shop/klantenservice/verzendkosten.html correct

Internet Explorer:

http://www.xxxxx.nl/net-shop/[b]fietskarren-nl[/b]/klantenservice/verzendkosten.html wrong

the part fietskarren-nl shouldn’t be there.

the url in the backoffice is just klantenservice/verzendkosten.html

the site root is http://www.xxxxx.nl/net-shop/

Someone has any idea?
