bottom post here (and trim your reply please), using that will have 
immediately noticed you replied to your mail and not to mine.

The difference between running ssh from shell and with cygstart
is that cygstart asks windows to do it and so the new process loses
the environment link with the running shell.

Pstree shows the cygstart process on new arms

?─┬─mintty───bash───mintty───bash
   ├─mintty───bash───pstree
   └─mintty───bash


You can see the differences running

  cygstart mintty
  cygstart mintty -

and than using `set` for both terminal.
In the first case the process is not starting a login shell (the - for 
mintty) and the two environments are slight different.

For what you are trying to do, you could use cygstart to run a login 
shell that executes the ssh command.

Regards
Marco
