speed it up
By chance I just used Excel 2002 the last days and it was so incredibly fast in all user operations.
At work I am forced to use Excel 365 on a modern windows laptop with fast processor and enough of memory. It is so sloooow in all operations: scrolling, switching between cells, typing, re-calculating.
On top of this I experience frequent failures (copy paste, formatting, ....)
How could you make a good working product performing such worse....
