Configuration Issue: add a active-trail class in the node's page

Hi again,

Now I have installed taxonomy menu trails with taxonomy menu module, the menu is correctly expanded on the node's page.

The issue I have now, is that the class "active-trail" is not added in the code source of the menu in the node's page.
That way, I cannot for exemple underline an active link in the menu of the node's page.

Is there a solution to add a active-trail class in the node's page?

Thank you!
