Chrome and menus not working

What has happened to Chrome? My own site, bought from Envato, some others I have looked at in preview, fail to react to menu clicks. My site works perfectly well in IE, Edge, & Firefox, but in Chrome fails to move when a menu item is selected.

	<nav id="nav-scroll">

		<ul class="navigation">
			<li class="active"><a href="#home">Home</a></li>
			<li><a href="#about">About</a></li>
			<li><a href="#portfolio">Programmes</a></li>
			<li><a href="#blog">Info</a></li>
			<li><a href="#contact">Contact</a></li>
			<li><a href="#player">Player</a></li>
		</ul>	

Does anyone have a way to get around this problem?
