Problem with cipaddressctrl

I am trying to use the CIPAddressCtrl and it has a very odd problem. When I use it in an dialog-based application's primary dialog it works correctly. When I use it in a pop-up dialog the problem appears - it does not accept three-digit address bytes.

Does anyone know what's going on with this?

What I have tried:

I tried to set the field ranges to go up to 255 and that made no difference. I tried Hans Dietrich's enhanced version here and it works correctly as it is the app's primary dialog. I added a button to his test app's main dialog that would bring up a secondary dialog and the problem showed up again. Here's the dialog code in case anyone wants to try it :

class CCtrlTestDlg : public CDialog
{
public:
	CCtrlTestDlg( CWnd* pParent = NULL ) : CDialog( IDD, pParent ) {}

	enum { IDD = IDD_TEST_DIALOG };

	CIPAddressCtrl		m_Address;

protected:
	virtual void DoDataExchange( CDataExchange* pDX )
	{
		__super::DoDataExchange( pDX );

		DDX_Control( pDX, IDC_TEST_ADDRESS, m_Address );
	}

	virtual BOOL OnInitDialog()
	{
		__super::OnInitDialog();
		return TRUE;  // return TRUE  unless you set the focus to a control
	}

	DECLARE_MESSAGE_MAP()
};

BEGIN_MESSAGE_MAP( CCtrlTestDlg, CDialog )
END_MESSAGE_MAP()

This uses a dialog with ID IDD_TEST_DIALOG and it has an IP Address control with ID IDC_TEST_ADDRESS and an OK button and that's it. I added a button to the app's dialog and when clicked it does this :

void CXIPAddressCtrlTestDlg::OnTestControl()
{
	CCtrlTestDlg dlg( this );
	dlg.DoModal();
}

The dialog resource is :

IDD_TEST_DIALOG DIALOGEX 0, 0, 180, 98
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION
CAPTION "Control Test"
FONT 8, "MS Shell Dlg", 400, 0, 0x1
BEGIN
    DEFPUSHBUTTON   "OK",IDOK,32,58,46,22
    PUSHBUTTON      "Cancel",IDCANCEL,100,58,46,22
    LTEXT           "Enter an Address:",IDC_STATIC,20,22,58,14,SS_CENTERIMAGE
    CONTROL         "IPAddress2",IDC_TEST_ADDRESS,"SysIPAddress32",WS_TABSTOP,81,22,74,14
END

and that's all there is to the testing dialog. This dialog can be added to practically any MFC app to check things out.

Two other pieces of info: when I remove the MFC subclassed control the same thing happens. Also, when I enter a third digit the control receives a command message of EN_MAXTEXT. That's the problem - I can't enter an address with any value above 99.
