ObjectVariableNotSetInspection ignores default member accesses.

[comintern]

Second issue with the same code as #2601:

In a UserForm with TextBox1 :

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    If TextBox1.Text = vbNullString Then
        MsgBox "Value required"
        Cancel = True
    End If
End Sub

The Cancel = True line triggers the ObjectVariableNotSetInspection (twice, but that's likely a different issue...). In this case, Set isn't required because the RHS of the assignment is a value type and the LHS is a reference type.
