We are currently experiencing problems with SafeAssign. From both the student and instructor point of view, SafeAssign is very slow. Students can submit assignments, but once they're submitted, if they click on the link for that assignment again, they get an error that says, "The specified object was not found." The assignment has submitted successfully, but the student can't get that confirmation.
Instructors can view these assignments by going to the Control Panel > Course Tools > SafeAssign > SafeAssignments. However, these assignments are not showing up in the Grade Center at all since March 10th.
This problem has been reported to Blackboard and we hope for a fix soon. In the meantime, the only way to grade these assignments is to view them via the Control Panel, write the grade down (yes, I really do mean use pen and paper... argh!) then once they've all been graded, go to the Grade Center and enter the grades.
