Dear all, nothing special done: open a session, moving to the target remote directory and local directory; afterwards downloading a WIndows .Net executable file. I would say a typcial standard situation in terms of how to use WinSCP. Regards Ronald

I was interrupted a couple of times during my session with the external server, but able to rectify by relogging in again. The error below showed up as the point that I close the WinSCP session when I was done.

It's simple enough. I've just installed this version and crash happens after I closed WinSCP. My PC was "waken-up" not rebooted if this might be important. I'll let you know if crash persists...

Opening a connection from the shortcut-menu on Windows 10 taskbar when said connection has a background-color causes fatal crash.
Works as expected, if the application is already open.
