Hi,

What has happened is after clicking the cell, you have pressed the F8
function key. Press the Esc key and click any cell to free the selection.

My problem is that when working in Excel 2003 I need to make a change on a
previously saved document. After opening the document up I select the cell
that needs to be changed and for whatever reason as I move the mouse up to
the tool bar to make the changes all cells that I move the mouse over
automatically highlight and I cannot make any changes or do anything else
with the document. What causes this and how can I fix the probem.
