This may not be the cause of the problem but is worth noting:
As of the 2.2.1 386 Development system, alignment of structures within
structures changed. If have programs compiled on both 2.2.0/386 and 2.2.1
or greater, there may be problems with on-disk data. Note: 2.2.1 DS was
the 2.2.0 DS with update #1 applied (UFC1). A simple test program that
just does a sizeof(struct) compiled under both will NOT show the difference,
you must print out the address of each structure member and see if they
match up. This only affects structure members that were not on 4 byte
boundaries.
