Depends on what browser you are using. Personally I would just click on the big X between the reload and home page icons. Of course if you are using a different browser to me then the icons might be different but you have to stop the download.
I have made a website like a scrolling paper, but when you get to the bottom of the page there is a small gap. I wont to make the page stop scrolling down all the way so you cant see the gap!
Maybe with a link we could understand what he meant.
Short answer, pages don't scroll by default, to stop it scrolling take out the code that you put in to make it scroll. On the other hand the OP could just be using the term "scroll" incorrectly.
