CListCtrl header will not resize

Hi,
I recently inherited a project with a CListCtrl problem I can't figure
out...
Its a Wizard app with a report type list on one page. What happens is
that the list box and header are all filled with the proper text,
however at runtime I'm unable to resize the columns using the list box
header. There is actually no response from the header at all, as if it
was disabled.
The code seems correct. If I create a small test dialog based app, the
header code works fine. I just can't figure what could be causing this
sort of behaviour?

Anyone have any ideas?

here's some code if it helps...

BOOL CDlgXXX::OnInitDialog()
{
  BOOL bRet = CDlgmainPage::OnInitDialog();

  SetupCtrlHeaders();

  return bRet;
}

void CDlgXXX::SetupCtrlHeaders()
{
    CHeaderCtrl* pHeaderCtrl = m_lstXXX.GetHeaderCtrl();
  if (NULL==pHeaderCtrl)
  {
    ASSERT(0);
    return;
 }

  LVCOLUMN col;
  memset(&col, 0, sizeof(col));

  col.fmt = LVCFMT_CENTER;
  col.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH | LVS_SHOWSELALWAYS;

  CString sLocalizedString;

  col.pszText = _T("");

  col.cx = 95;
  m_iColIndexPackageName = m_lstXXX.InsertColumn(pHeaderCtrl-


  col.cx = 80;
  m_iColIndexProgress = m_lstXXX.InsertColumn(pHeaderCtrl-


  m_iColIndexBitrate = m_lstXXX.InsertColumn(pHeaderCtrl-


  m_iColIndexTimeEst = m_lstXXX.InsertColumn(pHeaderCtrl-


  SetColumnLables();
}

void CDlgXXX::SetColumnLables()
{
  LVCOLUMN col;
  memset(&col, 0, sizeof(col));

  col.fmt = LVCFMT_CENTER;
  col.mask = LVCF_FMT |LVCF_TEXT;

  CString sXXXString;

  GetFromIntID(IDS_NAME, sXXXString);
  col.pszText = sLocalizedString.GetBuffer(sXXXString.GetLength());
  m_lstXXX.SetColumn(m_iColIndexPN, &col);

  GetFromIntID(IDS_XXX, sLocalizedString);
  col.pszText = sXXXString.GetBuffer(sXXXString.GetLength());
  m_lstXXX.SetColumn(m_iColIndexP, &col);

  GetFromIntID(IDS_XXX2, sLocalizedString);
  col.pszText = sXXXString.GetBuffer(sXXXString.GetLength());
  m_lstXXX.SetColumn(m_iColIndexBit, &col);

  GetFromIntID(IDS_TIME, sLocalizedString);
  col.pszText = sXXXString.GetBuffer(sXXXString.GetLength());
  m_lstXXX.SetColumn(m_iColIndexTime, &col);
}
