I was doing a quick check to see if a set of credentials were good so I just waited for the connection to be established, saw the list of files and then clicked the small "x" on the right side of the session name tab. That was the only active tab so the result should have been to close WinSCP.

As a test I tried the same steps again and it closed correctly without failing.

I was trying to log in to our Internal FTP. The folder from my last session has a lot of files in it and I expect that is the issue as I was having the same problem late yesterday too. It is taking too long to load. The folder that I need access to right now is not the same one it is trying to bring up. I won't be able to change the directory until WinSCP fully downloads the data. Now WinSCP is not responding :(

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

When I have two sessions open, one to a local Raspberry Pi and one to a webserver, sometimes when one of the sessions disconnects because of a drop is connectivity WinSCP gives the error below. It cannot be closed either from the application window or the taskbar. It can only be closed from the Task Manager.
The problem cannot be reproduced on demand but does happen every few days.
