In IE, the H2 and P text are invisible. If I click near the upper left hand corner and drag across and down, the text appears. But if I go to another tab on my desktop, or even another IE tab, and then return, it's gone again.
You didn't say which IE this was, but without looking at your page, my very first thought was the Usual Suspect: Haslayout.
Are you familiar with it? In IE6 it could make make lots of things disappear: backgrounds, text, floated menu items. Sometimes an action like hovering or clicking would make something appear or disappear.
IE7's not so bad, but also has HasLayout.

Well, I "solved" the problem by wrapping the disappearing content in a new div and styling the div with "zoom: 1.0". Seems like a ridiculous thing to have to do, but it works and I guess that's all I care about for right now...
