@bmercer: 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.)>
I was connected to an SFTP server, and I was trying to move a selection of remote files to a different folder. I had done the same operation multiple times before, but this time when I tried it I got an error that I had been disconnected. i reconnected my session, and when I retried the operation I got this error.

I believe this can be reproduced but not consistently.

The problem happens rarely. I cannot reproduce it.

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.

I was moving multiple files on a remote server into a non-existing directory which I include when asked for the target directory.

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.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
Contact to server allowed only few minutes -> need for resuming access
<If relevant, consider attaching a session log file or a screenshot)>

I worked normal with some SFTP and marked two files. Then suddenly the message appeared, that the connection is lost and I confirm the reconnect. After successfull reconnect, I press DEL key on keyboard, because the files were still marked. And then I got this error message.
