I wonder why, then, I see only the records in my buffer being retrieved (In
Monitor) and not all the records leading up to the start of the buffer
record.
I do notice that my habit is not to call IB_Query.Refresh, but to call
transaction.Refresh. Does this make a difference? And why do I not see all
records being retrieved?
