I am puzzled  by something and hope maybe you can help.  We are still using the Gradebook.  A teacher says when she enters a NHI in her gradebook for a student, then at a later date the student hands in the assignment and then the teacher enters a percent score, then mysteriously after a couple days the score reverts back to NHI.  I am not able to replicate the problem.  Have you ever seen this?  It makes no sense to me.

Thanks for your help,
