My freeware QuotesTK application automatically "re-downloads" all
historical quotes back to a user set date when a split occurs. I'm
working on allowing user defined stock lists but right now it is only
the major indices.

all data back to the first day are adjusted
(not just the date of the
split at which you see a gap). Unless your
downloader recognizes splits,
etc. and then overwrites previously
collected data (I don't know of any
that do) it is necessary to
delete all data and download all of the
adjusted data from the first
date.
