Good afternoon,

I've created a spreadsheet that has multiple Validated cells.  Each of
these cells is validated using a list, with "In-cell Dropdown"
Checked. However the drop down is not showing. The cell is still being
validated as I cannot enter a value other than what is in the list.

Also,  on the formula auditing bar, the Trace Precedents, Remove
Precedents, Trace Dependants, Remove Dependants, Remove all arrows and
Trace Error buttons are all greyed out.

I've checked that the sheets and workbook are not protected and as far
as I can tell it has happened between file save from yesterday and
today.

A new workbook does not exhibit these issues, so I'm sure it has
something to do with the file itself.

Am I missing something simple?
