As an admin and other teachers in the course, the gradebook always displays fine for us, no matter what settings we chose.  But, we have a particular instructor where the display is all messed up if he goes into the gradebook settings and chooses to show the total and override columns.  The display of the grades is no longer centered in the field, and the box is only as wide as what needs to be displayed.  We have tried everything that we can think fo including enenrolling him and putting him back in the course. trying it from different computers, like I said it works fine for every other admin and teacher.
