Hello,
A co-worker of mine received an excel file in the mail with one column
highlighted or bordered in blue lines (though the borders in format cells
were cleared). When he went to the upper right corner of the top most cell
in the column, the arrow became 45deg angle down to the right.

We have no idea what this is. Can you please enlighten?

Excel 2003 on XP Pro.

Thanks.
