Hi Caden,

Thanks for the bug report.  I am happy to report that your hunch about
case in/sensitive filenames was correct.  There are new distribution
packages available on the website now that should be more robust to
this issue.  Please download the new jar and see if it works this
time.  It worked on my Windows 7 installation.

A couple of other comments in the spirit of collaboration:
- To my great consternation, java's "-classpath" command line
parameter is completely ignored when "-jar <jar file>" is also
present.  The CLASSPATH environment variable is ignored as well.  Only
the classpath specified in the jar file's manifest is recognized.  Not
ideal, in my opinion.
- The program that is executed with the command "java -jar
LBJCoref.jar <text file>" is designed to take a plain, unannotated
text file as input.

Of course, neither of these were the cause of the bug; I just thought
you might like to know.

Thanks again,
 - Nick
