Upgraded Win7 to Win7sp1, in order to allow upgrade from ie9 to ie11. Install not straightforward and no confirmation if install was seen for ie11. Have checked version on 'about' screen, and it is ie11 (v 11.0.9600.17501 , update version 11.0.15 KB3008923.
Suspected Javascript failure as video on BBC sites don't load. Have checked in 'Tools' 'Advanced' on menu for script related options but am unclear about all options.
Any help appreciated.
