Inaccurate logging of accuracy

hmmz... with the code you describe pretty much any response will be
logged as 1, unless the response is identical to the one specified
under 'correctresp' so I'd tend to think that there then is something
wrong with he correct responses you specified there.

What is the true response slide??

I do think it's puzzling that the whole thing doesn't respond in the
way you would expect but if you got your program working than that's
great news :)
