  46 # The ActiveX module from Acrobat 7.0 has changed and it seems to now
  47 # require much more from the container than what our wx.activex module
  48 # provides.  If we try to use it via wx.activex then Acrobat crashes.
  49 # So instead we will use Internet Explorer (via the win32com modules
  50 # so we can use better dynamic dispatch) and embed the Acrobat control
  51 # within that.  Acrobat provides the IAcroAXDocShim COM class that is
  52 # accessible via the IE window's Document property after a PDF file
  53 # has been loaded.
  54 #
  55 # Details of the Acrobat reader methods can be found in
  56 # http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/iac/IACOverview.pdf
