I know from personal experience that check files work for OGR, at
least on the Win98 client.  You just have to set it up as described in
the help file.


There is some good information in the FAQ for OGR at:



I do have a suggestion.  My desktop PC can only do three or four OCRs
a day.  That is on a duel 500Mhz Celeron machine (7.39 Mnode/sec).  24
work units is far too large for a default buffer.  My poor notebook
will probably never complete it's 24 units.  It has been chewing on
one unit for a week with very little progress. I will sneaker net to
my desktop once I work the desktop's buffer down.
