I am getting (what I think is) an erroneous "do you want to save your
changes?" message when I exit my .xls file (even though I didn't change any
data).

It happens ONLY after I rest the highlight on a cell in which there's a
pull-down list (data validation). Again, I merely REST the highlight on the
cell ... I don't pull the list down or choose any data. Excel is acting as
if I did change data (hence the "save changes?" exit message) but I didn't
change data. Is that how a data-validated cell is supposed to work ... that
if I just rest the highlight on the cell, that Excel thinks I changed the
data in that cell? (As long as I don't move the cell-highlight to a
data-validated cell, I don't get the save changes? message.)

More info, just in case it matters: the cell (B93) is a merged cell
(B93:F93). When I go to data validation, I get a message that says: "the
selection contains some cells that do not contain Data Validation settings.
Do you want to extend data validation to these cells?" I answer "yes," and
the form comes up fine, with the proper data validation. But could this have
something to do with the erroneous exit message?
