Not working in Chrome under W10

The cesium hello world demo (https://cesiumjs.org/Cesium/Apps/HelloWorld.html) doesn't run in Chrome (Version 44.0.2403.157 m) on my W10 box, nor do any Cesium apps (raceQs), but they do run in Microsoft Edge and IE 10.
The openGL (http://get.webgl.org/)test runs correctly in Chrome.
Any suggestions?

Hello,

I’m not sure what would be causing this problem. What happens when you try to load the app? Are there any error messages in the console?

Have you tried clearing your cache?

Best,

Hannah
