Cells Being Highlighted by Mouse

[Paul]

Sometimes each cell on a worksheet becomes highlighted as
I move the mouse over it; furthermore, I am prevented from
entering any data in any cell. I do not know what causes
this -- or how to stop/prevent it. My only option is to
close the worksheet. Any advice would be greatly
appreciated. Thank you.
