@ericpell: 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.

When I opened the program WinSCP, it would show the message "Invalid access to memory" and I could not log in to my SFTP server to access the files. Please help to fix it and I need to access the files inside the SFTP program for my work.

Please find my below SFTP server name and login name for your reference. Hope it could be fixed as soon as possible. Thank you.
