This has never happened before.

I had left open but had not used a WinSCP session for a day or so.
I opened a new session and had left the previous session open as well.
After I opened the website for the new session, I closed the previous session.
This occurred just after I closed the older session.

This error came up when trying to close a Linux connection. I right clicked the tab and selected 'Disconnect'.

O/S: Windows 10 Enterprise 64-bit; 8GB RAM; Citrix VDI; WinSCP installed on "C:\Program Files (x86)\WinSCP"

WinSCP.ini was copied from a different machine onto this new VDI. Full permissions are set for the current domain user logged in.

When I reopened the same session and disconnected again, the error didn't come up.

Hi,
I had a couple of SFTP sessions open to the same server in the same WINSCP client but to different folders and was viewing some small files in the editor. When I had finished I was closed down the editor window and then isconnected one of the sessions when this error appeared. I could not reproduce.
