When I select "Assign a New Path ..." from the context menu of item(s) in the Downloading Files list, it does seem to update the target directory "behind the scenes", but the path displayed in the UI list and item properties remain the original path. Even if I stop and restart Newsbin the UI still shows the original path but the downloads seem to go to the new path. Strange and confusing.
