Work Computer Hijinks

The courtesy computer at work has been reconfigured with some program called "site kiosk" that severely limits access to computer functions. I've been using Mozilla Firefox in the past to work there, now I'm forced onto a custom version of Internet Explorer that doesn't even feature tabbed browsing or the ability to open a new window. I may have to bring a Puppy Linux CD-Rom and a USB key so that I don't have to put up with this silliness.
