Apologies to all Windows users, but my revised version of TreeForm does not seem to run on your system due to the fact that Java developers have effectively ruined internationalization for windows runs. It will be a least 1 month before I can even begin to have time to address this issue.
I now have SourceForge automatically send you version 1.03 (as TreeFormWindows.zip) if you are running Windows, and that one should work for most users still. Apple users still benefit from the new and improved version.
Apologies for the inconvenience.
