Maybe this is not related to putty/ssh.

You can have this behavior if you did started from this unix shell some services that are expected to return some exit code.

From the ssh manual:

----
ssh needs to hang, because it needs to wait:

* until it can be sure that command does not need more input.
* until it can be sure that command does not produce more output.
* until command exits because sshd needs to tell the exit status from command to ssh.

Best regards,
Horia.

Shalom,

This happens to me when I fire up a X/Motif application from ssh like this:

xclock &

That backgrounds it, but its still talking to the terminal session. So if I try to exit it hangs the session.
