Graphic Not Staying Where I Want It To

So as the title says, I have this graphic I want to stay in the bottom right
corner if the browser window (no matter how the window is sized). I've used the
following....

<div id="ClubAnnounce" style="z-index: 0; position: absolute; right: 0px;
bottom: 0px;"><img src="ClubAnnounce.png" width="234" height="444" /></div>

... and as I said it works in all my browsers except InternetExplorer. In IE
the graphic does stay to the right but it's gone to the top of the window to
the point where only the bottom 5 (or so) pixels of the image are visible. The
image is there, just off the top of the window.

Any help is appreciated. Thanks!
