IE 11 Anchor click issues

Question on IE 11 browser:
There is a web site which works fine for anchors in web pages upto IE 9, but when tried with IE 11 the anchors do not work for the same page. This is something weird. Every web developer would expect anchors should work in higher version like IE 11. Is there a fix available from Microsoft for such issues? If it requires compatibility then entire web pages would require fixes which again worse. Any help on this is appreciated from Microsoft Support team. 

Thanks,
Raj
