If a matching-type lesson is set up with reasonably long questions (multiple words, 50 characters or more), it displays in Internet Explorer with answer boxes aligned vertically at the right-hand side of the page and questions right-justified to their left. This layout, though slightly odd, is stable i.e., it does not change as the user selects the various choices. In Firefox, however, the layout is initially centred, with one long line for each question and its answer box. This looks good. However, as soon as the first choice is made, the layout collapses to an unsatisfactory narrow tabular form, with multiple line questions.

To demonstrate, just set up a two-part question containing questions like "aaa aaa aaa aaa aaa aaa aaa aaa" and "bbb bbb bbb bbb bbb bbb bbb" and answers "a" and "b".
