I had been using WinSCP and left for a few hours. I think Windows Home 8.1 went into sleep mode or hibernation mode and
when I woke it up the whole system was unresponsive to window clicks, or right or left mouse clicks.
The system is an I7 Processor with 8GB ram.

WinSCP was in sync mode and I had left it idle. After I came back after 1 hour this error appeared.

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.
