I am using the latest version of Jira (4.4) with the built in Greenhopper plugin (5.7). I saw in the video that you can sort task cards on the rapid board by dragging them up and down. I am not able to do this. I have "Rank" set as the ranking field in the Greenhopper config. I can see the rank field in each issue on the board, but I can't edit it.
Thanks in advance for any help with this issue.
