CSS (?) Problem with Sidebar in MSIE

I’ve done a few tweaks to the default WordPress theme (the one based on Kubrick), and I’m quite happy with how it looks in Firefox (for both Mac and Windows users). But in Internet Explorer, the sidebar disappears and the bottoms of the pages are cut off (both the last entries and the footer).

I know there’s a difference in how MSIE renders widths when margins and padding are involved, and I’ve tried to take that into account using some hacks:

page {
	background-color: #35190b;
	background: #35190b;
	color: #FFE4E1;
	margin: 20px auto;
	padding: 0;
	width: 860px;
	border: 0px solid #959596;
	}

/* Hide from IE-Mac \*/
html>body #page {
	background-color: #35190b;
	background: #35190b;
	color: #FFE4E1;
	margin: 20px auto;
	padding: 0;
	width: 900px;
	border: 0px solid #959596;
	width/**/:/**/ 860px;
}
/* End hide */

I’ve played with the width of the page to compensate for possible overflows. I checked the sizes of any images to make sure they aren’t too big. I validated the code at validator.w3.org, and it all checks out.

I’ve searched around various fora and haven’t found a solution that works.

I’m using WordPress 2.6, and the address of my site is http://worldtreephotography.com/wordpress/. Any suggestions would be greatly appreciated.
