Seo Url Links Problem

[flashback]

For some reason when I activate the ULTIMATE SEO URLS I get an error on some of the links that appear on my "Shopping Cart" sidebox for some reason when I click them from there they go to the index page instead the product page, it doesnt happen with all of the products just with some,something that I noticed is that the links that are different on the "Shopping Cart" box are the ones with the problems for example:

The Linking:

It won't work with the following URL on the "Shopping Cart" box:
/index.php?main_page=product_info&products_id=5:5407046bc1400d78c5501f2679e5dd77


It will work if I click the same product from the "New Products" section but the link looks different:

/index.php?main_page=product_info&products_id=5

On another item that is on the shopping cart box that have the URL:

/index.php?main_page=product_info&products_id=3

the problem wont happen there, I guess it has something to do with the URL.


Of course if I turn off SEO URLS everything start working perferct again.


My Zen Cart is the 1.37.1


Heeelp please :)


Thanks

If you are using SEO URL's you should wonder why the shopping cart isn't using the SEO URL's there....maybe you didn't install everything?
