[Typo3-shop] Problems with finalizing order in tt_products

[Jesper Scheuer Nielsen]

I have a multilanguage site where i'm trying to set up tt_products.

It's working fine in Firefox, but when i switch to Internet Explorer (IE) I 
can't get to the page where I'm supposed to put in my informations.

In IE there's always the language parameter (&L=1) appended to the pagename 
ex: http://mypage.com/index.php?id=17&L=1 and I guess that means that the 
site is calling http://mypage.com/index.php?17&L=1&backPID=17 and that's 
whats causing the problem.

In Firefox, no matter the language parameter, the info-screen is showing 
fine on http://mypage.com/index.php?17&backPID=17.

Does anyone have a solution for fixing this...it would be really welcome :-)

Regards,

Jesper
