I am running xcel xp on a windows 10 computer. I was trying to add a hyper link to a workbook. When I tried to paste the link into the worksheet xcel closed. I tried several times with the same result. I did some testing and now I find that when trying to create a new work book xcel will close if I try to enter numeric data into two cells in the same row. I can add numeric data to more than one cell in the same column. If I open a work created previously to the start of the problem the problem does not occur.
If I add alpha/numeric data such as q23ft or 32wt56 to cells in the same row the problem does not occur.
