Tutorial bumps down page content in IE9

[daGUY]

When I launch a tutorial in IE9, it bumps down the entire page content by ~50px, but, curiously, the arrows continue to pop up in their original positions (in other words, they appear where they're supposed to, but end up misaligned because the page content behind them has shifted down). No other browser I've tested (Safari, Firefox, Chrome) shifts the page content at all when the tutorial is active.
