Hi Derek,
Ok That is very strange. I cannot reproduce this on any of my data. A
quick couple of extra questions:
1) Does this still happen when you set start=0?
2) What is the chunksize of this data set (are you at a boundary)?
3) Could you send us the full table information, ie repr(table).
Be Well
Anthony
