Just found Net::SSH::W32Perl today, and found the same problem.   Note the thread at NET::SSH::W32PERL - script Hangs when trying to run a command where same complaint is raised - hanging at the same point.   Has anyone gotten Net:SSH::* to work on Win32 in recent times?

Hey, just found rebuilt for AS 5.8.x. I'll see what happens if I _can_ uninstall Net::SSH::* and reinstall from his site. (sigh)
