With the whole sheet selected (Ctrl+A on an empty sheet), Fill Down,
Right, Up and Left tried to fill all 17 billion cells and ran out of
memory, and Remove Duplicates scanned every row for minutes. Fill Up
and Fill Left also took their source row or column before narrowing the
selection to the data, so they filled up to row 1,048,576 even when the
sheet had data.
Whole rows and columns now narrow to the used range before anything
else (nothing to do on an empty sheet), Remove Duplicates works on the
active cell of an empty sheet, and a fill of more than 5,000,000 cells
is refused, as Auto Fill already does.
