WinSCP 5.9.4 release doesnt allow drag-and-drop from folders into ftp directories

Hello, since this update, we cant drag and drop from folders directly into ftp directories. Can you fix it?

After i changed from commander to explorer and restarted wincsp drag and drop works in 5.9.3 version. I am going to try to 5.9.4.
Okay i tested it. It seems to be some bug when you first installed it. Then i restarted it and now its fine. Thanks.:)
