Content box selection kills layout

Adding content to the top right content box on the home page is screwing up the page layout -- as in the content well (only) is horribly misaligned and the boxes are stacked vertically.

The bad layout reminds me of when there is a missing </div> but I don't see one.

This happens when I add a new or previous post to the hpfeatured box's category, which is "Arcadia blogs."

The problem posts show up fine in other featured boxes.

If I assign the post to a second category (say "The Latest"), then the layout is OK and the post appears in both boxes with no damage to the layout. Unchecking the second category kills the layout again.

Thought the cause may be the need for specific theme coding in the theme options file (see sticky above), but that did not help.

The top right box is this:

<div id="homepageright">

<div class="hpfeatured">

thanks.
