Is it possible that you've forgotten to set the 'length' field before 
calling GetWindowPlacement?  This kept me fooled for ages.  Here's a 
snippet of code which I use to maximize my app's window:

void CMainFrame::Maximize()
{
  WINDOWPLACEMENT wp;
  
  // must set the struct length BEFORE calling GetWindowPlacement
  
  wp.length = sizeof wp;

  VERIFY(GetWindowPlacement(&wp));

  wp.flags = 0;
  wp.showCmd = SW_SHOWMAXIMIZED;

  VERIFY(SetWindowPlacement(&wp));
}

Good luck

Just call "ShowWindow"!
