Double scrollbar in chrome? Css overflow

Hi all - I'm just after 1 scrollbar on the right, the vertical one. For some reason, the below code is producing 2 scrollbars. Any fix?

Basically, I just want a vertical scrollbar - regardless of res or if the window is resized. Any suggestions please?

html, body {
    height: 100%;
    text-align: center;
    overflow: -moz-scrollbars-vertical;
    overflow-x: hidden;
    overflow-y: scroll;
}

Code (markup):

If you remove Overflow-y: scroll then it doesn't appear. You have specified you want a scrollbar on your body div as well as the one normally on the browser

 

Thank you, that worked. When the window is resized, it won't horizontally scroll now. It's tricky
