I often open resources by dragging the reference links to them. However, there appears to be a bug whereby this doesn't work for some pseudepigraphal works, e.g. Psalms of Solomon, 1 Enoch, etc.
To reproduce, just find a reference to one of those books (e.g. here), and then try to drag the reference to a new panel.
