Opera always crashes when trying to add a Bookmarks Bar sub-folder to the Speed Dial page via the "Save as Speed Dial Folder" right click on the sub-folder. Moving the sub-folder to top level Bookmarks bar folder allows the Save to occur.

Running Opera for Windows latest release (occurred in previous releases) and Win10 latest updates.

Tried to search for this in forums but no luck with my search terms. Any thoughts, anyone? Is this just a bug or is there a config setting I need to pay attention to?
