IE7 disappearing box

[bp_travis]

In IE7, the box on the left of this page is disappearing halfway down the page. How can I fix this? Note: It doesn't do it in any other browser (IE6, IE8, FF, Safari, etc.).

Possibly the peekaboo bug (http://www.brownbatterystudios.com/sixthings/2007/01/06/css-first-aid-for-ie-peekaboo-bug/) caused by an element not having hasLayout (http://www.satzansatz.de/cssd/onhavinglayout.html).

Thanks for the tip, but unfortunately, I used some of the methods described on that site and none helped.
