@me4anicman: Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

When connecting to a SFTP server and if I direct download a file is gets upset and locks up. This is the first time I saw an actual log as I usually wait a few minutes and then just taskman kill it. If I choose download in background things seem to work fine.
