Detach ssh from bash in Cygwin?

I'm using OpenSSH in Cygwin under WinXP. I can set up POP3 port
forwarding (for Forte Agent) from within the bash shell in Cygwin, but
when I close the bash window, it shuts down the ssh process that is
doing the forwarding for me.

This doesn't happen with ssh-agent; that process keeps running after
the bash window closes.

Is there a way to detach the ssh process from the shell so I can close
the window without killing it?

I think I've tried all combinations of putting an & at the end of the
ssh command line, and putting a -f option in it, so far with no luck.

For example, here's a command line I've tried:

ssh -N -f -L 2110:mailhost.com:110 dmurdoch@mailhost.com &

This installs the tunneling and things work fine until I try to close
the window with "exit"; then the window won't close until I click on
the frame to close it, at which time Windows says "Windows cannot
close this program ....", and if I tell it to "End now", the ssh
process goes away too.
