Unless I hit enter or tab, I often get 2 or more cells when I'm trying to
select only one cell. eg. I click in a cell to enter info or to add or
delete a row and I get 2 or more columns selected or 2 or more rows. The
only way I can select one cell at a time is to right click in the cell. How
do I prevent the multiple selection of cells from happening. This is very
time consuming.
