Thad's obviously hit the nail on the head here, but
presumably it is potentially dangerous to set those
registry keys to 0 since they will cancel the
increased security in the Local Zone for HTML which is
implemented by SP2's Local Machine Lockdown.

There's a linked page detailing developer implications
at:
http://msdn.microsoft.com/security/productinfo/XPSP2/securebrowsing/lockdown_devimp.aspx

This suggests a number of alternative solutions,
including saving files as HTA instead of HTML to give
different security zone settings, or adding a "mark of
the web" comment in the HTML files along the lines of:
<!-- saved from url=(0020)http://www.dqsd.net/ -->
to give the HTML the same security zone settings as
the source website

There's also mention of:
"creat[ing] a separate application that hosts the HTML
content Internet Explorer Web Object Control (WebOC).
The HTML is then no longer bound by the same rules
that apply to content run in Internet Explorer. When
the HTML content runs in that other process, it can
have full rights as defined by the developer or zone
policy for that process."
