Coming back to the first div

Hi,

I have a menu toggling down divs which works properly, but I'd like the last div toggled not to be remembered. I want my links to lead to the first div every time they are clicked. I can't desactivate this "memory" option.

anyone has a clue ?

here's a test version of the site :
