I'm trying to sort upon a given column and I get the error message stating
that "Merged cells must be of the same size."

I know what merged cells are, but the problem is, I cannot find ANY cells in
the column in which I am sorting that are merged. So does this rule apply to
ANY CELL in ANY column? If so, how do I bypass or shut off this feature so
that I can perform what I thought was going to be a simple sorting of date on
a single field?
