I have checked the Options, Advanced, Editing Options, to ensure 'Enable fill handle and cell drag-and-drop' checkbox is selected. I have also made sure 'Formula - Calculation Options' is set to Automatic.
My mouse pointer still will not change to a 'move pointer'. Therefore, I am unable to use the Fill handle to copy a formula down a column.
I am even unable to a value increment, for example, 5, 6, 7, 8, 9 10
