<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
<If relevant, consider attaching a session log file or a screenshot)>
I connected to a server, then I left the PC. A day after, when I logged in, the connection cannot be reseted, because it needed a VPN, so the Winscp showed me a dialog, that cannot reconnect to the server. I canceled the dialog, and connected to another connection (to a different one). When it connected, I could not clicked to anything. I pressed Alt+F4 to restart the program, and this report dialog came up.
Cannot focus a disabled or invisible window
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.
