Herman,

I'm still thinking about this one ... it would be nice to know the 
cause before trying to work around it.

I did two tests today:

- 600 symbols (S&P500 plus a few) ... 3000 * 1 min bars == 6 days == 
93kb per bar ... downloaded all OK .... eS DataManager popped up a 
warning at approx 30/60/90% of download == every 200 symbols ... I 
clicked OK and the download sailed on .... it would have kept going 
even if I hadn't acknowledged the popup.

- 500 symbols (S&P) ... 100,000 * 1 min bars == 208 days == 3125KB 
per bar == way over the max possible bakfill (approx 6 months for 1 
min bars) ... download locked up after only 4% == approx 20 
symbols ... this is way below the cumulative byte for 200 symbols * 
backfill limit .... no warning about exceeding symbol limit.

I am not sure about what the cause is ... eS fault, AB plugin fault 
OR throttling by eS OR something else.
