The following code updates a 'date edited' column in a worksheet we use.
However, it also seems to disable the undo command. I understand not being
able to edit the changes vba makes, but you cant undo an edit you make. this
is probably because vba is making a change after everything you edit. Is
there any way to re-enable Undo?
