In Excel 2000 and earlier versions, you can change the selection in a
locked cell's data validation dropdown, if the list is from a range on
the worksheet.

If the list is typed in the data validation dialog box, the selection
can't be changed.

In Excel 2002 and later versions, neither type of dropdown list can be
changed if the cell is locked and the sheet is protected.

This MSKB article has information on the previous behaviour:

How can I "disable" a Drop down list (but still have it in use if the
overall Sheet protection is off)?

I thought it would work via the Sheet Protection, but my sheet is protected
(as are the cells locked where the Drop down is) but I still get the option
of picking from the DV Drop down

Thanks
