Unable to open emails in Hotmail as of 11-12-13

Clicking on emails does nothing as of the above date.  The only way to look at new emails that I have found to work is to right click and choose reply in the dropdown.  (Unfortunately there is no simply 'open' in that dropdown.)  I do note that Internet Explorer 11 was downloaded yesterday as well, and I am wondering if that is adversely affecting the operation of Hotmail.  Please advise.  (Note: temp internet files are deleted routinely so there should be no adverse effect there)
