Do you have JavaScript turned off? If it's turned off the picture site's navigation won't work. Is your security setting cranked all the way up (Tools | Internet Options | Security)? Try setting it to "medium" --that might help.
When you're dealing with Microsoft, it <i>never</i> pays to jump on the new-technology bandwagon. Microsoft saves money by letting the general public do their beta testing for free (in the software engineering industry, testing is one of the most expensive parts of software development). I recommend you go back to Internet Explorer 5.5 until Internet Explorer 6.0 is officially released (even then I recommend you wait until the first couple of revisions are out).
Good luck!
