Moving bookmarks in bookmark manager freezes/crashes Opera
Using 42.0.2393.94 (but similar happened with earlier versions).
Opened Show All Bookmarks, created a new folder within another folder, highlighted several bookmarks and dragged them to new folder; Opera froze, then quit and restarted.
Nothing was lost, bookmarks were not in new folder. This is not a major issue, of course, but something is funny here.
