Ok, one possibility which is rare but I have seen.  If the Shrinkit
archive was created with Shrink II on a Mac, ShrinkitGS may not be able to
extract it.  Ususally ShrinkitGS can, but accasionally no.  The Balloon
NDA on the GS can unshrink these files however.  (I think Balloon and
Shrink II were done by the same group of programmers at EGO Systems?)  At
one time I thought I had figured out the reason, but I was never sure. The
files always had weird file attributes - like no guest access on a file
server.  In other words, they appeared to ShrinkitGS that read/write was
not allowed; but Balloon didn't care while extracting the archive.
Apparently Shrink II didn't care either when creating or extracting the
archive.  It has been a couple years since I last had this problem and I
may recall the facts exactly.

If you think you have a good shrinkit archive and ShrinkitGS doesn't work,
try the Balloon NDA if you have it.  If both Balloon and Shrinkit fail,
the archive is somehow corrupted.  Also make sure it isn't really a .BXY
file (shrinkit with binary II header although both GSShrinkit and Balloon
handle this OK IIRC).  A Shrinkit with a MacBinary header would be
trouble.
