I want to execute a specific routine whenever a cell of a certain column
changes.

All is OK if I press enter and the cursor is programmed to stay in the cell.
Then I check the ActiveCell.Column property and execute the code. I have a
problem if the user leaves the cell i.e. with a right or left arrow and the
active column upon execution of the Worksheet Change routine is different to
the one I wish to monitor.

Is there a way to know the address of the cell that triggered the Change
Event instead of the current/active cell ?
