Step to reproduce:

1. Connect to VPN service.
2. Connect to server via SCP protocol using username and password
3. Successfully connect
4. Browse somewhere
5. Disconnect VPN
6. WinSCP attempt to reconnect, I try to close connection window, it show "Cancelling..."
7. And, program error. I can't close WinSCP. I have to force close using Task manager.

WinSCP 5.13.5

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.

Thanks for your report.
