Long filenames in student submitted files can prevent assignment marking

If a student uploads a file with a long filename and the teacher has a lower resolution monitor (e.g. 1024x768), then it becomes impossible to mark any of the assignments as the part of the table with the 'Grade' buttons is off the screen and there is no scroll bar available to reach it.

(See attached screenshots for clarification - 1st shows 1024x768 resolution, with grade buttons unavailable; 2nd shows 1280x1024 resolution, where grading is possible)
