You are forced to authenticate every time you request a page. The reason
you don't get prompted every time is that your browser caches the
authentication information and sends it with each request. The timeouts it
the squid.conf just affect how long squid caches the authentication
information. When you authenticate to squid, it remembers the username and
password that worked before. If you set to timeout to 5 minutes, it will
only remember the username and password for five minutes, and after that
will pass that info back through your authenticate_program.

Most likely you have RealPlayer G2 running in your system tray. It doesn't
know how to do proxy authentication. I noticed that machines that had
installed RealPlayer prior to my requiring authentication kept trying every
minute even though they were always getting rejected. I could not get fresh
installs after I required authentication to mimic this.
