We have rolled out Office 2007 across the company, and this week I have had
two users with the same problem.

The have a calculation in a cell that the copy down. The formula is correct
right down the column, i.e. A1+B1 goes to A2+B2 etc... but the value all the
way down is the same as the first cell the formula is copied from. There are
no absolute values in the formula.

Is there a fix for the obvious bug? At present we can't trust Excel.
