When I use Tex for multiple choice responses, I end up getting multiple listings in the item analysis for the values. I've tried everything I can think of and in every other respect, things are fine. The images are rendered correctly, the items are scored correctly. Any one have any thoughts?
It's a known bug (MDL-12418) but fixing it was only possible with big changes that were not suitable for the stable branch, so you will have to wait until Moodle 2.0 is released for a fix. Sorry.
Thanks. It's just an inconvenience but not critical.
