Hi. I keep using the program and it's good most of the time.
But I got one tiny problem. We often have conectivity problems at our office, when the connection is off for a few minutes. Sometimes (just sometimes, not every time!) when that happens WinSCP makes the system very slow and almost unresponsive. It tries to reconnect or something, and that takes too much resources (CPU %) I guess. I can't even run task manager to kill it. I can switch to any other application except WinSCP, but I can't actually do snything in those applications either. That lasts several minutes, after that the WinSCP window is finally closed (I click the cross button many times during the slowdown), and then the system is suddenly alive. Note that at that moment the internet connection is not on yet.
I guess the problem is in some connection function inside Windows or smth like that but I can't say for sure.
This is not a frequent problem but you might consider it.
