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.

@contact: 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.

Hello Martin,

As a matter of fact, I downloaded the application again and then re-installed over it and everything went back to normal. Thanks for taking the time to read and reply.

Sincerely
C.Thierry

@cthierry: Thanks for your feedback.
