swapping byte order

What Tim writes is correct if you want to do this but the "wait" you are
experiencing is almost certainly not due to swopping. If you loading wormbase it
is a large database and acedb now keeps an in memory index of tags per object
which will take some time to load. (Once loaded it speeds up queries massively)
So while there is no harm in doing what Tim suggests, you will still have a
delay while the loading of the index occurs.

cheers Ed
