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 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.

@khodadadi.mit: 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 dragging a file to be copied while another copy was still in progress.

WinSCP 6.1.1

Error message:
Copying files from remote side failed.

Invalid access to memory.
