Header links are in fronpage (joomla 1.7-1.6)

This is in joomla 1.6 and joomla 1.7.

This issue is because there is not any menu link to those articles and can not take the item id.
You can do the following.
Go in Menus / about joomla (or bottom menu). There click in new.
In "Menu Item Type" click select and chose "Category Blog".
Enter any menu title example Header.
In Required Settings In "Choose a category" select  Header.
Click Save.

Like this you will get the links to the directory of header category and not in front page.
