We upgraded from Moodle 2.7 to 2.9 and lost the frozen, static students column, wherein the column displaying the students' names used to remain fixed when scrolling horizontally through the multiple assignments in the gradebook. Without this feature, it's quite difficult to grade. Does anyone know how to fix this and freeze the column so it remains while scrolling horizontally?
Note: we are using the Moodle theme Sky High. I'm not sure if this is a 2.9 issue or a theme problem.
