You can set or reset enablement by going to the Control Panel, expanding Course Tools, and selecting the Respondus Lockdown Browser option. Regardless from where a test originates, when it is deployed in a course it can have Respondus Lockdown Browser enabled to work with it. If not done when uploading from Respondus 4.0, the exams can then be deployed in the course for students to take. Once uploaded to the Blackboard shell the exam is indistinguishable from ones created in the Blackboard Test Canvas.
Mostly because using the Respondus test manager requires the additional step of uploading the exam into the Blackboard course shell. The Blackboard test creation system is better when creating new individual questions. Where Respondus 4.0 excels is in it's ability to automatically convert properly formatted word documents into an online exam format. Respondus 4.0 and Blackboard both allow the instructor to create/originate tests within their respective applications.
