Is there any way to determine what is triggering a name to recalculate?

I'm trying to get rid of all the volatile Dynamic Range Names in my workbook. IOW: I'm trying to get rid of "Offset(....)" in my Range Names.

I have a Range Name that uses a UDF() 2 times. I have verified that the UDF() has "Application.Volatile False" as it's first line. The UDF() is being executed hundreds of times when I move my cursor.

Is there some way to determine what cells are triggering the Range Name to recalculate?
Or maybe an explanation of why the UDF() is being triggered when all I do is move my cursor?

Here are the UDF() and Range Names. $A$13 and $A$15 have #s in them (no formulas).

Function WC(ByVal r As Range) As Range
    Application.Volatile False

    If Not r Is Nothing Then
        Set WC = r.Cells(1, 1).EntireColumn
    End If
End Function

Range Name: BaseCol
ReversTo: =WC($CC$22)

Range Name: Base
RefersTo: =INDEX(BaseCol,$A$13):INDEX(BaseCol,$A$15)
