if i remember right you are using a windows XP computer browsing on Internet Explorer. try the following:
Click start>control panel
open "internet options"
click the "advanced" tab
select the "reset" button at the bottom of the window
close any open internet explorer windows and try viewing this topic again.
let us know if that works!
[EDIT]
also make sure that your computer is updated to the latest software and security fixes by going to
www.windowsupdate.com or if you are running windows vista update your computer from the control panel.
make sure to grab ALL available updates as this will most likely fix your issue and make your computer run better!
