We have a user computer running Windows 10 with recent upgrade of Office 2013 from Office 2010.
The user has to open up multiple Excel documents on that computer from the local C drive. Those Excel documents were created in Office 2007 and 2010.
Occassionally, when she was in the middle of working on one of the opened documents, the spreadsheet freezes. She clicks on anywhere on the spreadsheet and it has no response. She is however able to save her document - this is the only good thing.
To gain control again, the user has to click the Excel icon and close all documents.
If you have a clue, please advise.
