Issues with Silverlight and IE11 mean some applications that need Silverlight won't work (Netflix and SKY GO for example).
CHROME browser has this issue fixed so you can use chrome for those applications which give problems with IE11.
If you need a video application in a popout window - for example sky go has an option for re-sizeable popout windows as well as full screen then do the following in chrome. You need to install the latest version of Silverlight first though.
1) allow popouts from the sky site
2) type in the chrome browser address bar CHROME:PLUGINS (if you see a smiley a colon should be typed in that place after the word CHROME)
3) enable (check the box) the Silverlight plugin
Works fine - Service guys at SKY just kept saying SKY GO doesn't work on Windows 8 -- and they hadn't even HEARD of windows 8.1 !!
Seems a fact of modern life - CALL CENTRES get more and more frustrating to use and completely useless.
