IE7 and fixed divs problem

Background

I need to do a rather complex layout for a client, using fixed DIV. Everything is fine in IE8, FF3 and Chrome, but IE7 mangles all the thing

Edit: The fixed DIVs are a must, only the content DIV must scroll (That is the spec, sorry)

HTML and CSS code

<body style="margin: 10px;">
<div id="wrapper" style="width: 960px; margin: 0 auto; position: relative;  border: 1px solid red; overflow: hidden;">

    <div id="header" style="position: fixed; width: 185px;  height: 600px;  top: 10px;  border: 1px solid blue;">
      header
    </div>

    <div id="content" style="width: 680px; float: left; background: white; margin-left: 185px;  min-height: 600px;  border: 1px solid lime;">
        content
    </div>

    <div id="rightcolumn" style="position: fixed; top: 10px; width: 90px; margin-left: 865px;   height: 600px;border: 1px solid maroon;">
        right
    </div>

Notes

I'm not so worried about IE6 because I know it does not support Fixed elements, but if you know how to fix it, great!

Questions

  1. What should I know about IE7 bugs to fix the problem?
  2. How can I reference the left in the header columns relatively to the wrapper
  3. Why the header column goes the the right and the right column disappears?
Solution

  • Found a fix!! Strange enough floating the content to right fixes it!
    Do I earn a cookie?
