Thanks Timo,

   FYI: What I actually saw is that unless LVM_GETBKCOLOR returned a
solid color (i.e. anything but -1) then the image specified by
LVM_GETBKIMAGE would keep on getting clobbered by the Program Manager
background. When LVM_GETBKCOLOR returned 1 (black), the image
specified by LVM_GETBKIMAGE would draw just fine.
