Named Anchor

Heh,
I have 3 items in my menu that links to the same page but to different places on that page. I’ve used named anchor to achieve that.

Problem is that the page goes back to top right after finishing loading.

The anchors work perfectly when I’m on the same page and hit the other menu item. But not when I come from another page.

I suspect a script to change my page length but cannot figure out how to override it.

any clues?
