[support] Menu and active trail not set correct

Hi all, I have created 3 links for my primary links: 1st set to <front> (set to node/1 in the admin section) 2nd set to a view page 3th set to another view page

now I need to write my primary links menu (I can not use theme_menu_link* functions) so I'm writing a function in template.php file, but I have notice a strange with 1st and 2nd link in the front page: active trail is set incorrectly: 1st have active_trail FALSE (but I'm in the front page) 2nd have active trail TRUE (error). (3th is correctly FALSE)

If I see the 3th url active trail is set correct: 1st FALSE 2nd FLASE 3th TRUE

Any idea ?

M.

PS: sorry for my english.
