I closed a dialog box that usually appears when I connect or reconnect to a Linux host via SSH. It's basically the banner telling me the OS version and other stuff. But, I think the reconnect was occurring while I was closing the lid on my laptop. When I opened it, and saw the WinSCP page, I went to close the dialog using the X in the upper right corner (not by clicking the OK button) and got the error.

Had an SCP session open which timed out. When clicking on this connection window, WinSCP tried to reconnect. This specific connection displays an authentication banner. WinSCPs authentication banner dialog appears. I tried to close it by clicking the dialog's "X" closing button, not by pressing any of the dialog buttons. Then the error popped up.

Btw: The "Report options" in the bug report should offer a third radio button for "I don't know / first time occurred".

@bill.evans: 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.

Suddenly this error message popped up, between multiple (at least 2) dialogs that say 'Please login with user ID and password'. I closed the first dialog, then got the error. The second dialog is still visible.

This happens, repeatedly, as follows:
1. I open a secure session which relies on my VPN.
2. My VPN closes, closing the secure session.
3. When I go to close the session "continue" dialog, I get this error

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.

Thank you. I tried to reproduce the issue with the debug module, but I could not. It seems this issue doesn't happen on the debug module...

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.

This error happened when getting the list of the root directory. The protocol was FTPS.
