@jtz123: 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.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>

Select an item in the directory tree then start typing.
Easily reproduce able and happens often.
Also sometimes get error: External exception EEFFACE

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

I was trying to change the directory, and connection was lost.
If the folder does not exist also, it should throw error, but lost connection and I had to reconnect.

I had downloaded a bunch of files. I used the top menu "Session" --> "Close Session". That caused the "Login" pop-up window to appear. I then clicked on the "Close" button on the "Login" pop-up window. At that point I got the List index out of bounds (-1) message. I tried to get it to do it again, but it didn't happen.

Long time (hours) between uses. When tried to copy files, this happened. Not sure if the VPN was active before the session started, but it is now. Seems to have taken down the server too (ubuntu 20.4).

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

It seems that changing to some script generated file directory causes this error. Here is the directory:

/home/ubuntu/Temp/horizon/N7rXlRU1ZFzxapySGl2g/

After a few attempts I can connect to this directory. If I try to switch to another one, it breaks as well. I found something related to "unicode".

Access through SSH (PuTTY) seems to work without issues.
