I was right, there IS an error, in a part of the code which I don't remember ever modifying. (A less than sign seems somehow to have been replaced by a greater than sign.)

The result is that the output is TOTALLY wrong.

I will check the program out carefully before I upload a new version.
If you have already downloaded, please ignore that version, and wait for the new one.

I will reset the time code so that you will still get a 30 day trail.

Thanks for the feedback, John.
