Time outs during assessments

If a user has not done anything in Blackboard for more than an hour, the next action will fail and generate a login prompt. Don't give students a long essay test on-line. If it takes longer than an hour they won't be able to submit it. Either make it a take home exam that they are to work on for a certain length of time, but not in Blackboard. they can submit their answer via Blackboard, but they will leave to compose their work offline. OK?
