Menue anchor links for one pagers don´t work in other pages.

Hi,

I´m building a site with Highend theme as a one pager. I´m also using the portfolio pages. Unfortunately the menu links, that are optimized for the one pager don´t work in other pages, like the portfolio detail pages. for instance one link is “#company”. In the portfolio page it doesn´t work, because it interpretes it as “http://domain.com/portfolio/#company” and not as “http://domain.com/#company”.

I tried it this way: “/#company”. Then it works in other pages, like portfolio pages, but not inside the one pager.

Inside of the one pager it works, when I scroll down a bit, so that I´m inside the sticky menu. But it doesn´t work, when I´m on top inside the normal menu.

Is there any other way to solve this problem?
