When dragging and dropping content items, the items may scroll way past the bottom of the browser window.
Blackboard are aware of the bug, but at the time of writing have no ETA on a fix.
Workaround – Use keyboard accessible reordering
- Click the icon at the top of the list you want to reorder. This is either  to the top right of the course menu, or  the top right of a page with reorderable content (eg content folder, announcements, test canvas, etc)
- In the list, click the item you wish to reorder
- Click the Move Up and Move Down icons until the item is in the place you require. (Jump back to step two if you need to reorder other items on the same page)
- Click Submit
