why doesn't homepage return to original scroll position

I noticed recently that when surfing web from yahoo homepage that when I return to homepage that its not in the same position as when I left it.
I have to scroll up or down to find where I left off.
This started several days ago.
This is not a major issue. I was just wondering if there may be a quick fix for this?
I am up to date with Windows, Adobe and Java and have Windows 8.1 and ie 11 browser.
