Gradebook

Hi,

We recently upgraded our Moodle to version 1.9.7. It works perfectly, apart from when in the Grade Book, when you hover over a grade it shows you the student name and which module it is, like the attached image.

However, in Internet Explorer 8, where the name and assignments should appear next to the grade you want, it is displaying off the screen, so you struggle to see it.

Does anyone know of a fix for this?

Thanks in advance,
Sam
