I have a similar setup and get the same result you do. Once the 1MByte
applet(?) downloaded it just sat there trying to load something else. The
problem is that their application (the applet) isn't proxy aware and tries
to connect directly to the bank. Here's my tcpdump output:

08:39:18.489062 myhost.citec.qld.gov.au.3774 > servicios.sudameris.com.co.http: S 3171224203:3171224203(0) win 16384 <mss 1460> (DF)

The bank's application is broken. Up until the applet starts running
everything connects via the proxies. Then the applet starts and wants to
go direct. After a couple of minutes it appears to give up and displays a
message:

                  Iniciando

                Banca Virtual

        Banco Sudameris Colombia

From there it appears "dead".
