   Well, I've got it working flawlessly now. :) In fact the problem was 
entirely related to one specific Borland compiler setting.  Allocate 
enums as int.  This was causing all sorts of problems.  I had to have 
this set or borland packs enums.  I was looking for the word 
"structure"and I didn't pay much attention to this setting.  Like I 
figured, it was something stupid on my end.
   Incidently, I changed (and have been changing) a lot of stuff over 
to Win32 API calls, memory and file handling.  It sure seems a lot 
faster now as opposed to using the standard C stuff, but this might be 
my imagination.  Maybe I'll add multi-threading now that I have a 
handle on this thing. :)


   Thanks for all the help.  You really cleared up a lot of things for 
me and I learned a LOT (About the JPEG code too. :) )

P.S.   If anyone reading this thread is interested in my hacked up 
version of the .LIB let me know.  I've been using it on hundreds of 
images now to make sure there are no strange memory leaks and it hasn't 
burped even once.
