pgAdmin III won't connect over ssh tunnel

Hi Folks,

I have searched the archive, and didn't find an answer, so excuse me if 
this has been addressed already.

I have the latest pgAdmin III running on Windoze XP. 

I set up an ssh tunnel to my server using cygwin's ssh client.
   ssh  -L 5433:remote1:5432 laramie@remote1

I use the cygwin psql client to connect from my localhost:
  psql --> ssh@localhost --> sshd@remote1 --> postmaster@remote1

with the command
  psql -h localhost -p 5433 -U laramie mydatabase

and this works.

Now, with pgAdmin III, I use the GUI, and I select
localhost
5433
SSL [no input]
and my password

I get the Connection refused dialog after a really long time.

My questions:
1) is it possible to change the connection timeout?
2) when I sniff the port on 5433 locally, I find that pgAdmin III is 
sending binary bytes, then hangs.  Is pgAdmin III insisting on SSL even 
though I told it not to?

Since this configuration works with the plain old command line client 
psql, I would assume that it would work with pgAdmin III.  I much prefer 
this port-forwarding setup, since I know and love ssh/sshd and I'm not 
all that interested in punching another hole in the server's firewall to 
allow postgress through.   Similarly, I know how to get ssh working with 
certificates, and don't want to have a separate process for installing 
certs for pg's clients.

Thanks,
Laramie
