Just a few of my thoughts for you to think about.
IE 11 was developed for Windows 8, then was modified for Windows 8.1 and subsequently adapted for Windows 7, by being 'patched-up'.
In view of the fact that IE 11 has developed numerous incompatibilities with a number of Internet sites, you are left with the alternatives of reverting to your previous edition of IE (probably IE 9) or adopting a more reliable Browser. My choice would be to avoid Google Chrome and settle for Firefox; which does have a similar feel to IE , but is more reliable.
