 Background colour on CAnimateCtrl problem


Visual C++ 5 / NT4.0 / Win95

I'm having a problem displaying an animation control above a list view.
The problem occurs when the standard window colour is not white, the
background of the animation does not match the rest of the window.
I am trying to make the animation transparent, and set the background
colour to the correct value by handling WM_CTLCOLOR in the view. The
following code works fine under Windows 95, but not under NT 4?

Could this be due to a difference in the CAnimateCtrl implementations in

the common control DLL's, or am I doing something wrong in the
WM_CTLCOLOR handler?

Any help would be much appreciated

/* Code sample follows - CxxxView derived from CListView */
// CAnimateCtrl m_anim

void CxxxView::OnInitialUpdate()
// ...
// Animation created normally, nothing special
  m_anim.Create( WS_CHILD
        CRect(100, 200,300,400), &(this->GetListCtrl()), ID_RESERVED);


HBRUSH CxxxView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
 HBRUSH hbr = CListView::OnCtlColor(pDC, pWnd, nCtlColor);

 if ( pWnd->m_hWnd == m_anim.m_hWnd)
        pDC->SetBkColor( GetSysColor(COLOR_WINDOW));
 return hbr;
