Multiple Cells/rows in Column selected when a single cell is click
 

I have a 2007 worksheet and when I select a cell by clicking in it, numerous
cells below the one I clicked are selected. It seems to be a random number
of cells and sometimes it happens and sometimes it does not--when the same
cell is selected. This means I cannot cut and paste because instead of a
single cell or row, numerous cells or rows are selected.
