If you read my message time-stamped 18:27:43 -0500, the problem is few
(if any) of US understood what sockscap WAS. Here's a WAG
(wild-ass-guess):
when a "new" application that sockscap has never seen before attemps to
call any WinSock functions, sockscap creates some sort of entry in the
registry FOR the application, where it will store information concerning
HOW this new application uses networking, what SOCKS protocol should be
used for it, etc. So, in this case, socks32.dll is creating registry
keys for ssh.exe, and hangs -- looks to me like socks32.dll has the bug,
not ssh. But, again, refer to sockscap FAQ#7 quoted in my other
message.

No, it's illegal to distribute binaries that use cygwin, without (a)
distributing the source, or (b) buying a proprietary cygwin license.
However, that doesn't apply to sockscap -- it doesn't "use" cygwin. See
my other messages.

It appears this is because sockscap "makes assumptions about the
application and stack implementation" that are not valid for f-secure
and now, cygwin.
