I've got Windows 7.  I can test if you outline a step-by-step.

Sure.  It's disturbingly simple.  I open up a new tab in my Internet Explorer 
8 window, type this into the top box, and press return. 

http://www.squeaksource.com/SqueakByExample.html

The text in the box changes to: 

http://www.squeaksource.com/@2RH_FUm3Eg_bB4Vf/7qNAMBqT

And I get the message:

On Windows 7 with IE8 I typed:   http://www.squeaksource.com/SqueakByExample   into the address bar and it seems to work fine,
changing the address bar to:  http://www.squeaksource.com/@Tn8orBHYjPJk26uc/2pR31wbz 

I then typed:   www.google.com   into the address bar,
followed by again typing:   http://www.squeaksource.com/SqueakByExample    into the address bar
and got:    http://www.squeaksource.com/@G9WiRi32jRcJqmrq/TjM5FQU6

I tried to reproduce your error by...
Going reviewing Safety > Web Page Privacy Report showing that a cookie was accepted.
Clicking on Settings, and then on the Internet Options dialog dragged the slider to Block All Cookies,
but that had no impact on viewing the page. 

You might anyway try: Safety > Delete Browsing History.
Sorry thats about all I can offer.
