This will fix the problem you had in your "names" quiz Adam.
While I was at it, I submitted some fixes for JCloze (jcl file) and JQuiz (jqz file) so that the size of text boxes depends on the length of the longest answer. Additionally, for JQuiz hybrid and shortanswer questions, if the answer is longer than 29 chars, a (multi-line) textarea will be shown instead of a (one-line) text box.
I made the above fixes to the HotPot module in Moodle 1.6 - 1.9, and the CVS HEAD branch which will one day become Moodle 2.0.
The modified scripts will be probably be available from CVS and the Moodle downloads page sometime soon after next Wednesday.
Adam, thanks again for reporting this problem
regards
Gordon
