i use WinSCP on many computers (i support you via patreon).
On one of my pc i used auto-Update to update to 5.14.2 beta 9079.
After the update, i cannot use drag and drop anymore. Just nothing happens when i try it.
I started a second computer with an older version: Drag and Drop worked, after update the same problem occurs.
I dont know the last working version i had before, usually a beta :-( but after downloading 5.13.6 everything works)
