Network Programming in .NET

If you use the jQuery.scrollTo, or a plugin dependant on it, such as

/**
* SmoothScroll

* Dual-licensed under the GPL and MIT licenses.
* All individual scripts remain property of their copyrighters.
* Date: 10-Sep-2013
* Version: 1.0.1
*/

/**
* jQuery.ScrollTo – Easy element scrolling using jQuery.
* Copyright (c) 2007-2013 Ariel Flesler – aflesler(at)gmail(dot)com | http://flesler.blogspot.com

*/

Then you may find on Chrome 61, the page refuses to scroll.

The solution, I found was to use these CSS classes for HTML and BODY

html {
    overflow: hidden;
    height: 100%;
}
body {
    height: 100%;
    overflow: auto;
}
