Custom control problem

I have a follow-up question on this.

I have made my custom control class and it seems to work, except for some 
layout oddities, here is a dialog that uses the control 5 times, shown for 
cases with 8 and 2 checkboxes in the custom control: 
<http://www.arnholm.org/tmp/wxIoPortCtrl_dialog.jpg>

I.e. I am able to populate the control with different number of checkboxes, 
but the layout of the result isn't entirely as expected (right adjusted), 
and I am not sure where/how it should be fixed. For the case where I use 8 
checkboxes it seems ok, but when I use only two, I get left-adjusted boxes 
on XP and spread out boxes on Linux/Kubuntu.

Here is how I populate the check boxes in a horizontal wxBoxSizer:

void wxIoPortCtrl::CreatePins(const wxString& flags)
{
   ClearPins();

   int number = flags.length();

   // reserve space in vector.
   // Not strictly required, but more optimal
   m_boxes.reserve(number);

   wxSize siz = wxSize(14,-1);

   // traverse string and create controls
   for(int ibox=0;ibox<number;ibox++) {

      // create checkbox with proper initial value
      wxCheckBox* CheckBox = new wxCheckBox(this,
                                                  wxNewId(),wxEmptyString,
                                                  wxDefaultPosition, siz,0,
                                                  wxDefaultValidator,_T("ID_CHECKBOX1"));
      if(flags.at(ibox) == wxT('0')) CheckBox->SetValue(false);
      else                           CheckBox->SetValue(true);

      // add box to sizer and our vector
      m_boxSizer->Add(CheckBox,1,wxALIGN_RIGHT|wxALIGN_CENTER_VERTICAL,5);
      m_boxes.push_back(CheckBox);
   }

   // recompute the control layout
   this->SetSizer(m_boxSizer);
   m_boxSizer->Fit(this);
   m_boxSizer->SetSizeHints(this);
   Layout();
}


I also call Layout(); in the dialog after this call.

Any ideas why I get different layout results?
