When you say dropped, is she still appearing in the course enrollment as suspended, or has she actually been deleted out of the course? I know suspended students will still see courses on the overview page your referring to (http://yourMoodle.org/grade/report/overview/index.php)
ahhhhh... That's what I needed to know.
The students are still enrolled in the class, but have had their enrollment suspended.
Thank you so much!
