Hi Claus,
Hmmm, I thought I saw results as you described them to be a couple of times in testing but now here is what I get.

I inserted your code snippet and added a deletion of column A.
Here is what I get, where the right hand column below was what I had in column A, A1 to A25 and the left hand column is the results starting in A3 to A14 after running the code.
