It's looking like some sort of java scripting screw-up with the host site not being called correctly.
Any chance you have java scripting and active x scripting disabled under Internet Options > Security > Custom > Scripting?
No alternate browser to test, I guess?
Can you download an attachment through e-mail? If yes, you might send me an e-mail and I'll return a zipped copy of HijackThis with instructions to run it, although I think this looks more like a corrupted IE or javascript problem.
Did the problem exist before the reinstall? If not, you might want to try it again.
It would be interesting to know if this site tells you you are JavaScript enabled:

Here is an MS article giving methods of reinstalling IE6 in XP. I'd try sfc /scannow first. I don't know if you can get a download from Microsoft, but if you can, Method2 might be best.

Wink: I would also suggest doing this: go to Internet Options and under Temporary Internet Files, click the Settings tab, then "View Objects".
Remove everything in that folder. And if you have any Download managers installed, uninstall it.
