Why does picking an cell highlight two cells?

[Jnight]

In an Excel 2007 worksheet, some cells when picked with the mouse highlight
the adjacent cell. The cells are not merged and data is only entered into
the cell that was picked.

Hi,

2 possibilities.

1. Tap F8. Did that cure it?

2. If it didn't take the zoom level up and down. There are reports of a bug
in Excel 2007 that causes this and reportedly changing the zoom level clears
the problem

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.
