Hello all,

I have a MacBook Pro that is 3 years old that has undergone some physical damage (a few drops). A few months ago, I was working on two Excel worksheets (one had >850 rows and 3 columns and one had >12000 rows and 24 columns) and a Word document (around 60 pages long).

When working with these three files, any type of copy and pasting led both Excel and Word to stop responding and eventually crash multiple times. Once I closed the smaller Excel file and Word document, the bigger Excel file was workable though slow. Is this a common problem with normally running worksheets of this size, especially with multiple files? Any information would be helpful. Thanks.
