title: Fixed Positioning breaking z-index
body: <p>I have a webpage that I need to modify, the background, which is currently absolute positioned with z-index to push it back, needs to stay put when scrolling, i need to change it to fixed, yet doing so seems to break z-index and push the content below it vertically.  Any ideas?</p>
  
  <p>edit:
  OK I managed to get it to work in FF, but IE is still broken...</p>
