Use full category tree for website links

[chimairax]

Hello,

I used "Use full category tree for product links" in order to show my customer the full breadcrumb when he access my website from another website.
But when I click a link inside my webpage (for example if I click a product from the home page) it keeps showing the top level category instead of all the children categories.

Example 2:

When I click a link outside my site the breadcrumbs are like:
Home -> Clothes -> Men -> T-Shirts -> Small
And below it shows the desired Small T-Shirt

But when I click the same product from the home page the breadcrumbs are like
Home -> Clothes
And below it shows the desired Small T-Shirt

I think this is not a breadcrumb problem, but a link url problem.

How can I fix this?
