Hi when i am on a folder

www.mysite.com/folder/

if i click lets say german its fine..

www.mysite.com/folder/lang/de/

but then it stickes and i can break out of it, say if i try to go to spanish i get this file with the error

www.mysite.com/lang/de/folder/lang/es/folder/

even trying to go back to english i get this

www.mysite.com/lang/de/folder/lang/en/folder/

it works fine on any non folder pages it can move throw the langs fine and it can break out.

but the folder options translate but won,t break out of that folder.???

anyone else seen this problem before or know how to fix it as i'm stumped
