[Solved] Filling a specific height in IE Win.

Hi all;

I'm laying out the footer of a fixed width site, and one part of its content needs to be a logo image (which I want to place as markup, not via CSS).
The text parts of the footer I have managed to get to fill the required height (3em) by setting the p tag to 100% height of its container but I can't use the same trick on the logo image as it stretches the image.

If anyone can help me to get the IE (Win) version looking the same as the Firefox version I'd be a happy chap. (IE Mac is all over the place, but one thing at a time)

I've separated out the relevant bits of the page and the css and put them online here as trimmed down files.
It's all valid apart from an underscore hack that I used in the css to give a height to IE(Win) only.

Can anyone help?
Many thanks
