Assignment

Hi, we're using the Humboldt Upload & Review assignment type in Moodle 1.6.1 and are having a problem with the reviewed files that teachers are uploading back into the assignment. Once a teacher uploads a file that has been corrected or marked up in Word, the reviewed file becomes invisible in the assignment. Any idea what's happening with this?

Also, in researching through the threads about AU, Upload & Review, and the new Upload (1.7 version), I'm thoroughly confused as to the future of this sort of an assignment type. What is currently in 1.7 that provides this sort of Upload & Review functionality and is it indeed backwards compatible with 1.6?

Finally, today when I went to make some changes that were recommended by Mark Pearson in lang/en_utf8/assignment.php, the changes were already present in my stock assignment.php file and included the necessary strings for the Upload & Review assignment type.

Thanks!
