Pretty sure this error occurred after my VPN timed out. VPN sessions are good for 12 hours, and I often leave WinSCP up and running when I walk away after being done. When the VPN expires, WinSCP will not have access to where it WAS logged into, so I'm guessing that's what threw the error.
<If relevant, consider attaching a session log file or a screenshot)>
Invalid access to memory.
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.
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.
