Hi Sian,
  Me again! Have just done a few tests, and it should converge if the
parameters are refined in the correct order. (At least it did with my
refinement, though I used a manual background and not a refinable one.)
The starting model does look bad starting with the crude model I freely
admit: one reason for using lead sulphate for teaching is that the refinement
of the structure is fairly tolerant of the starting model.
  Hope this all helps - if not, just bug me again about it.
         Cheers, Jeremy.
