[CONFIRMED: IE9 suffers the same bug! :'( ]

I have a div that is like a photo-frame style thing, which contains an img, and two divs. This outer div has a max-width (80%) that works beautifully.

Problem is, if I set a max-height, I get the following behaviour:

80px - works as expected.
80em - works as expected.
80% - same as height:auto and no max-height.

Any advice? Doc-type is <!doctype html>, which is entirely valid, and normally works perfectly. I even added <meta http-equiv="X-UA-Compatible" content="IE=9"> out of frustration.

EDIT:

This here is the html/css that I believe is relevant:

<!doctype>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=9"> 
<script type="text/javascript" src="https://getfirebug.com/firebug-lite-beta.js"></script>
<style type="text/css">

You need to take a new approach to this - using max-height to scale an image is simply the wrong way to go about it, and you will most likely never get to a point where you like the solution.

If I was you, I'd go back to the drawing board and rethink the layout (not the design, just the markup & css) and try to reach the design goal another way.

Use * html for ie.

* html .whatever{
height:100%;
}

For what you're doing, it'd be easier to just set the image container to have a nice margin and set the max width to 100%. You probably don't want to force the max-height to be smaller than the viewport anyways since people are accustomed to scrolling vertically to see large/long images.
