IE7 (yes, you heard me) and captions

Hi all

You did read that subject line correctly – I am in the unenviable position of having to fix some issues with a blog and IE7. Yay!

We’re using a child theme of Twenty Eleven on 3.3.1 and the image captions are not showing up on IE7. The captions do appear in the source code. The blog is in Chinese, but it doesn’t appear to be an issue with a language pack, because colleagues that have the Chinese language pack installed also can’t see the captions in IE7.

First question:
Do you think this is a stylesheet problem, or a functionality problem?

Question the second:
Assuming it’s a stylesheet problem, any ideas on what it could be? Alignment? Margin? Padding?

Third:
If a functionality problem, which file do you think I need to dig into to solve this?

Here are the styles for the captions from my child theme’s style.css

p img,
.wp-caption {
	margin-top: 0.4em;
}
.wp-caption {
	background: #eee;
	margin-bottom: 1.625em;
	max-width: 96%;
	padding: 9px;
}
.wp-caption img {
	display: block;
	margin: 0 auto;
	max-width: 98%;
}
.wp-caption .wp-caption-text,
.gallery-caption {
	color: #666;
	font-family: Georgia, serif;
	font-size: 12px;
}
.wp-caption .wp-caption-text {
	margin-bottom: 0.6em;
	padding: 10px 0 5px 40px;
	position: relative;
}
.wp-caption .wp-caption-text:before {
	color: #666;
	content: '\2014';
	font-size: 14px;
	font-style: normal;
	font-weight: bold;
	margin-right: 5px;
	position: absolute;
	left: 10px;
	top: 7px;
}

Thanks all!
