Grading in Blackboard

This version is not near as friendly for grading discussion posts.  When I go to "Needs Grading" much of the time I can't even access it as i get a sad face with "preview-learn.blackboard.com redirected you too many times"

When it does open so I can grade it, it does not forward me to the next user needing a grade, but I have to go to "needs grading" again.

Anyone have a suggestion?

Thanks
