Perhaps you or your students have come across this issue: after accessing your course shell you find you can see the Announcements page but little else. The Course Menu and Control Panel are nowhere to be seen!
This happens because Blackboard has a feature which allows users to extend the content palette across the entire width of the course canvas. But in so doing the menus get hidden.
The resolution is simple: click the arrow icon located about halfway down the left-hand margin of the page and the Announcements Panel will snap back to reveal both the Course Menu and the Control Panel.
