In prior versions of Excel (2013 & earlier ) I was able to load many files (up to 25) and effortlessly work with all copying & pasting but since Ofgice 365 2016 Excel always fails and stops working when working with these same files and requires a restart if Excel.


Also, after pasting from one wirkbook to another the cursor hangs as a cross and nothing can be done further until the wirkbook is closed then reopened! PAIN!!!! Any ideas on what's the problem and how to fix it?
