Are you saying that your ssh may use a different cygwin1.dll than the rest of the system? If so, delete it. In fact I would recommend completely removing the old OpenSSH stuff (you can keep the id_rsa file) and installing the latest ssh version. About your other problems, the hypothesis that network administrators have altered the file permissions is quite plausible. The fact that h:\tmp\tg.pl is on a network drive also makes it harder to determine what's the expected behavior.
