[galaxy-user] Trying to "unshare" a history in order to delete

Hi, I shared a history with another user and I am now trying to delete said history. When I go to delete it I am told to unshare it first. I found one message in the [dev] list which says to click the "shared" link when viewing Saved Histories and choose "unshare". When I do this nothing happens. When I had the other user (who has a button which says "unshare" for this history) click "unshare" that user is told they can't unshare it. How to go about this? Jen, maybe you can add deleting shared histories to your deleting/disk space video? Thanks, David FHCRC
