dif Ubound for member array when debugging

I have a dynamic array designed to hold a user defined type, both of which
are declared as follows:
Private m_filterRestore() As udt_filterRestoreData
Private Type udt_filterRestoreData
m_wksName As String
m_colName As String
m_index As Integer
m_filter As Filter
End Type

When I run a test in the debugger, stepping through it, the array is
correctly dimensioned (for this test) with elements 0 through 4. When I let
it run without stepping through it, however, it is dimensioned with elements
0 through 10, with elements 5 through 10 holding empty udts. The code is
below, and I sure don't get it.

This is a long one, so I really do appreciate the time.

Thanks, Eric

Pepper your code with Debug.Print UBound(m_FilterRestore) before and
after each ReDim Preserve. also Debug.Print the array size variables
and a descriptive label telling which line the Redim occurred.

Run in once in the debugger and again without the debugger. Check the
differences in the output to find out where the problem lies.
