Many times if I get something wrong, whatever the reaosn, I am NOT allowed to correct the naswer. Whatever I do to select it, I can't. This may be browser specific because I have seen problems with there is a change of focus across browsing. It may be something script or site specific, no clue there. Don't have a debugger on this one because it runs too slow. Anyway, I have to submit the wrong answer twice in many cases to free up the entry field to be able to edit and correct the mistake.
