This morning, Excel is pegging out at 100% of CPU usage. Things as simple as adding a row are taking more than a minute to execute.
One other strange thing is every time I save the workbook as XLSX I'm warned that I will lose the macros. From what I see, there are no macros. (Yes. This spreadsheet was sent to me to work on. Someone else built it.)
Might these issues be related?
