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 started a couple of releases back, but I think it started in the middle of a version, so I don't think it was anything related to an update.

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 connected to a remote host, and wanted to download some files.
I stepped away from my PC for a short while, before starting the download.
I then came back and clicked on Download, in the background it then popped up with a reconnection to the server, and then the download failed.
Once the connection was re-established, the download worked fine.

My first time seeing this happen, I have gone through roughly the same set of steps before and not seen this (or any other) errors. I see that I have not upgraded to the latest, I will attempt to re-create with similar steps after upgrading.

Brought up WinSCP, connected to Linux host via secure FTP, started background download of large (~5gb) file from host; after starting download, set WinSCP to sleep after it completes. All apparently went as planned, file download was completed and system was in sleep the next morning.

Upon startup, *many* "Invalid access to memory" dialogs appeared before this one.

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.

I tried to move a number of directories in the root of a cloud storage device to another existing directory in the same root. The first subdirectory to be moved existed already in the target subdirectory. WinSCP gave an error message and I choosed to skip this (because I knew there was a chance that one or more directories already existed). I assumed WinSCP would continue with the next directory, bu instead I got this error.
