Carlos,
  Good idea, and thanks for the reply. Unfortunately, the script still 
hangs at the same point. I've done a bit more work and an essentially 
equivilant C script also hangs at this point, so I doubt that this is a 
D-problem. All the same, any help from this great community is very much 
appreciated :).

  Thanks again,
