You've accidently hit the Scroll Lock key. Just press it again. It's
usually just above the Home key

Normally, I push arrows and selected cell highlight moves one space left,
right, up or down. All of a sudden, cell selection can only be down by mouse
and when I push arrows the cell selection remains constant and instead the
worksheet moves on the screen. Also, when I hit enter, it no longer drops to
next cell position. Help!!!
