When manualsort is active and I drag&drop a file within the same lister (I drop on an empty area), drop menu doesn't show up (tried with details and list view).
I'm not sure but I think it did show up in 12.7
v12.8 x64
Edit: Of course I'm dragging&dropping it with right mouse button.
I'm not sure at the moment but I might have been trying to drag a file from 7zip to DOpus to the same path (like move a file from C:\ to C:) and this was why it didn't work (and it wouldn't regardless of whether manualsort was active or not). I'll let you know if I run into this issue again.
