1. Toss tracks in the Play Queue.
2. Select the Play Queue source.
3. Attempt to use drag and drop to rearrange the tracks.

Expected results:

Tracks are reordered according to my preference.

Actual results:

While dragging it looks like the drop is going to work, but actually nothing happens, and the track order is not changed.

Workaround:

Clear queue, re-add tracks in desired play order.  Try to remember what you were doing before you got sucked into this... :-P


Sorting also doesn't work, but that behavior makes sense to me (assuming you can manually reorder the tracks).
