I had a URL that I was trying to drag to FileVoyager (to the second pane that was set to “display current pane in details mode”) from a browser. It showed the shortcut icon as the mouse cursor, but when I released the mouse button, FileVoyager crashed (disappeared). I tried it twice. The URL that I dragged (in case that is important) was https://www.fachords.com/guitar-fretboard-notes/
May be related. When I dragged a file from another app (PaperPort) to a directory in the left-most window, FileVoyager seemed to hang (Task Manager Power usage was very high), and I could not kill FileVoyager even using the standard exit controls. I had to End task in Task Manager). The transfer actually took place, but nothing in FileVoyager responded to mouse clicks.
