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.

@w.tarnawski: 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.
