Anyway, I've to share my observations. Based on your script, I've made something interesting here : http://www.thewhitehotel.be/pages/white_room_super.htm.
Online it only works in FF, but on my PC, on the first test I've made, it works well in both browser... Now, when I moved the test file from the root to my pages folder, it forget to work in IE while not giving any errors... (same issue when I uploaded it).
Could you explain that ? Is that a Ghost in the shell?
Thanks in advance if you have a answer for me.
