I would like to run a macro when a specific cell is clicked. I have tried a Worksheet_SelectionChange(ByVal Target As Range)macro and it worked however it cleared the undo/redo contents which is a problem. Is there a way to trigger a macro on a specific other than using the SelectionChange event? I am trying to expand the width of a data validation list when a user clicks the drop-down button so the user can view the entire contents of the list. I am using Excel 2000. I cannot merge 2 cells as there is data in the cell to the right and left of this cell.
