   Again, I'm not certain which version it occured in (I think I skipped
the 1.01 release), but there are incompatabilities between v0.92 and v1.0x
.ZIP files.  On the v1.02 release, a special program was included to update
the .ZIP files.  This was probably mentioned in the v1.01 material.  Other
than these incompatabilities between .ZIP files, nothing else could be wrong
_except_ for blown .ZIP files.  If the latter problem existed, the unzip
utility would be printing messages noting CRC errors.  Therefore, it must be
a ZIP version problem.

  I suggested the 1.02 release (instead of 'upgrade') since my version included
programs which would change v0.92 .ZIP files into 1.0x compatable .ZIP files.
It may very well be that v1.01 had these same files.  I do not know.  Reading
of the information file in the 1.02 release explains how the 0.92 .ZIP files
can be updated for 1.0x compatability.  (I assume the person who launched this
thread has read the appropriate information files provided in the ZIP archive.)
