Error skipping startup message. Your shell is probably incompatible with the application (BASH is recommended).
WinSCP v5.5.1 and I also tried older revisions as well, 5.2.4.
Client OS: Windows 7. Tried on 64bit and 32bit systems.
Using Linux (RHEL/ubuntu) SCP, Putty SCP, Cygwin SCP, all work fine.
The device uses NetBSD 5.0 for SSH services.
