Richard,   I have the deepest respect for you ( I used to hunt out and read your messages in 
comp.lang.prolog back in the 80's.) 
However, I am afraid that this is a trifle disingenuous.

Although you are a novice at Morphic, you have far more computer science and software development experience than most people around.

I would suggest that Lilly ( the student who had difficulty with radio buttons ) and her teacher
are extremely unlikely to be within several orders of magnitude of your competence and knowledge.

( I am assuming that you are the Richard O'Keefe of Quintus Prolog fame and who wrote The Craft of Prolog )
