This link was helpful. However, the link information says the green shading is because it was a resubmitted assignment or quiz. It was not. I was a discussion board post. To answer your questions:
1. Yes, in SpeedGrader, the points are there for the student.
2. Yes, I can see the points are included with the other points on the right side of the screen.
3. No, there are other details. Everyone else's grades are showing. I allow releasing grades when entered.
4. Dates are correct.
Chris, I appreciate all of the information you have sent me. As I said, I've never seen this before. I guess I'm just going to not worry about it!! Thanks, Shawnna
