I see this error for the first time. It repeats at this stage, I just cannot create new file.
I try to create new file at server side (SHIFT+F4). There is file MultiTPManager4.cs at Linux ssh server and I try to create new file MultiTPManager4_.cs. File MultiTPManager4.cs is selected, I press SHIFT+F4 and in the dialog I modify filename from MultiTPManager4.cs to MultiTPManager4_.cs. Once I press ENTER, I see the error. File MultiTPManager4.cs is already opened in the text editor (WinSCP). MultiTPManager4.cs was modified but not saved. Once I closed it, I was able to create my new file, MultiTPManager4_.cs. I see clear relation between opened (modified) file MultiTPManager4.cs and error when I tried to create new file (MultiTPManager4_.cs)

WinSCP runs in VirtualBox with Win10-x32, it works OK until today. WinSCP and Win10 is up and running for several days, maybe a month... Several text files (.cs) are already opened. In most cases I create file at Linux and WinScp only opens it and I do changes as I fix bugs in the code.

The problem happens rarely. I cannot reproduce it.

In WinSCP, I reconnected my session, then tried to open a log file that I had previously viewed a few days ago. I got the error message below, so I refreshed the directory and tried opening the file again.
See attached screenshot.
I tried opening some of the other files and got the same error.
By the way, I have some windows updates that are staged waiting for me to reboot. I will try that, but will lose this internet session when I do it. If I can get back to this posting I will let you know the outcome.

The problem happens rarely. I cannot reproduce it.

- When i let the tunnel connection idle for three days and let it disconnect, and then create a new tab on WinSCP, this error pops up preventing me to create the new tab. Already open tabs can reconnect as usual. Happens rarely.

I made some file transfer, then left connection open but idle in background.
Connection was via a SSH port-forward using SOCKS proxy.
Later the SOCKS proxy closed unexpectedly, so the connection was lost.
When I return to computer 6-7 hours later the error message was popup on the screen.
