The problem happens rarely. I cannot reproduce it.

WinSCP downloading in the background while minimized to tray. So far, it has happened repeatedly while downloading from a particular directory. It has happened both while using the computer for other tasks and while not using the computer for anything else.

WinSCP 6.1

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.
