dinamic menu in 2,1

Hi , i have made a dynamic menu on wordpress, and i have a static front page, all goes well until I click on one post in the blog page, if i click on the menu that is on the header inside a post , i get page not Found,

on a post when I hover the mouse on the home or other link i get the coorect page name, but on a link inside the post

https://localhost/~faustopacheco/wordpress/blog/2007/05/teste/home

Is this a permalink configuration error? i ahve
