Yep, that's the way we all run by default (see cygwin.bat).  I agree
that if you're having problems getting bash to behave, it's best to focus
on that issue first.  Your ssh problems may just be another symptom of
the same thing.  How about sending cygcheck output
(<http://cygwin.com/problems.html>)?  There may be something helpful in
that which someone on the list might pick up on.
