One simple thing to try, that won't do you any harm but does often clear up screwy browser behavior:
Empty your Temporary Internet Files folder. In IE, this is a matter of choosing Tools-->Internet Options, and then looking for the "Temporary Files"/"Temporary Internet Files" section. Your mileage may vary by OS and version of IE--for example, my IE 7 on XP x64 has a "Delete" button on the General tab under the "Browsing History" section. Tell it just to delete the files (you can leave cookies, history, etc. if you like).
Then check the size of the temporary files folder. Make sure it's not more than about 50MB. This won't affect you downloading stuff bigger than 50MB, but it *will* keep your browser from filling your hard-drive with crap that it then can't find.
If that doesn't help...
I find more page issues (and JavaScript errors) when I have the Phishing Filter on. You might consider turning it off long enough to try again, and see if that's the problem. Or see if adding "forums.station.sony.com" to a list of "Allowable Sites" in your Internet Options clears it up.
Basically, what IE Security (and the Phishing Filter) do, is try to make some decisions about whether the page you are loading really is secure. They don't always guess right, but they'll err on the side of caution, blocking and/or shutting down content and page behavior just in case.
When you tell it a particular site is allowed, anything coming from that domain is "whitelisted", or rather, not checked as closely.
If neither of these solves the problem...
Then it's time to look more closely at detailed browser settings: specifically, how it allows scripted content and/or ActiveX controls to run. Hopefully you won't reach that point, though.
