Thanks Dan for testing. A few thoughts:
- Security. Can you access the directory and write the files?
- On Windows there is a java.exe and a javaw.exe. The first version allocates a console window where you get error messages. The javaw.exe does not allocate a console windows, yet the program writes some info to the console window. Maybe that is the error.
- I would imagine that 'somewhere' the stacktrace is available. That would be helpful.
This week Thursday I may have a Mac to try myself.
