Improvements to the programs


We would be grateful for any suggestions for improvements to the program -just email us [email protected] or use the contact form on our web site:


We would also like to be informed of any apparent faults or mistakes, but please first look at the notes on troubleshooting and potentials, fields and contours near to boundaries, and also look at HELP!. If you have found an apparent fault it would help us very much if you could email us copies of the data files that show it, and could tell us the sequence of events (if relevant).


The CPO programs have a comprehensive set of traps, so that informative error messages almost always appear when a program stops, but see the notes on crashing for information on the events that have not yet been trapped or are impossible to trap..
