Any (possibly preliminary score) entered in the "Score" box when grading a written submission causes the page to automatically submit that score to the grade book if the instructor clicks anywhere else on the same page, without even moving to another student's work, regardless of whether they have pressed "Submit" or not. This is a serious --- and potentially legal -- issue:
It should be up to the instructor grading an assignment to decide when they are ready to submit a score, and not the learning management system.
For instance, if you have typed in a preliminary score, but are not yet ready to submit it, then the score currently in the box should *NOT* automatically trigger a submission upon losing focus
