I.E. box positioning with a twist

I am using a page both as-is and as the right part of a frameset.
Everything looks fine in Mozilla, all the elements validate (HTML and
CSS), but the framed version seems to fall victim of the I.E. box model
bug: the right column overlaps with and covers the left edge of the
middle column.

Example:

original page: http://www.web-ho.com/test/main.html

framed page: http://www.web-ho.com/test/frameset.html

The unframed page cannot be changed, it is generated by a blog authoring
program (Word Press); the question is therefore how to change the CSS so
that I can fix the overlap when the page is presented in a frame *without*
changing it when it is presented full-window.

[According to Eric Meyer, with my frameset declaration with URI, I.E.
should be in strict mode, so I don't know why I'm having the problem:

Thanks,
