I was running OS 10.11.2 / Parallels11.1.2 / Windows 7 and Office for Windows 2010 and everything worked fine. I wanted some of the newer features of Office for Windows 2016 so upgraded from 2010 to 2016 and now have a problem. The three key Office for Windows 2016 applications I use -- Excel, Outlook and Word -- freeze (i.e. the area above the menu bar read "Not Responding") forcing me into task manager to shut down the application. The freezing problem is so bad / frequent that the applications are unusable. I would appreciate any insight / solutions people have to fix this problem. Thanks!
