Hi, I am new to Squeak but not to general programming.  I am trying to do
some of the tutorials using Scamper within Squeak 3.2, but can't get
through our firewall.  I just get, for example, the message:

"error occured retrieving http://minnow.cc.gatech.edu/squeak: Server
minnow.cc.gatech.edu is not responding"

When normally using Internet Explorer, the firewall proxy server is set up
in the Internet Options, and when I then request a page that requires
Internet access, I get prompted for a userid and password to authenticate
to the firewall.

In Squeak, I see some code in the HTTP protocol that looks like it is set
up to use such a proxy, and there is code somewhere (in Scamper I think?)
that looks like it automatically requests a userid/password when a
particular HTTP status code is received, but somehow I never get prompted
for the firewall.  Scamper just goes directly to the message above.

Is there something easy that I am missing here?  How can I make this work?
