CPU-usage indicates high percentages

CPU-usage indicates high percentages

Hi there,

Today I was working at home and at the office with several computers and tried to import sheet files from Excel. Importing went well but when I tried to work with it I saw the CPU indicating just below 100% voor iexplore. When I tried to reach other cells in the sheet it lasted several seconds or more.

I hope you can provide the solution.

Many thanks

Nico
