The proxy only setup will break all applications that do not know how to
talk to proxys.... A transparent proxy setup is one where all the traffic
is directed throught squid reguardless of the client configuration. You
can find more information about this type of setup here:
http://www.linuxdoc.org/HOWTO/mini/TransparentProxy-2.html

The reason your application is failing is probably because it was not
desinged to work with any http proxy that is not transparent.
