Right sidebar renders incorrectly on homepage in IE8, Firefox OK

The problem: IE8 renders right sidebar under the center column on the home page instead of alongside it.

UsingFirefox (3.5.7): The latest WordPress (2.9.1), Atahualpa (3.4.5.1), the blog renders as it should, All works as always.

Using IE8 (8.0.7600.1685) the following happens:

• Right sidebar renders below the center column.
• Does not display the topmost 'text' widget containing HTML
• Does not render any prior posts below the misplaced sidebar although Atahualpa is set to display 5 full posts in "Configure Excerpts"

This does not occur on "Page" pages, Single Posts, Category Pages or Archive Pages ... only on Homepage,

Any idea what the culprit might be?

I rarely use IE so I haven't a clue when this symptom appeared. Don't know if it relates to WordPress 2.9.1 or updated Atahualpa.

Thanks for any clues.
