Hi!
I'm not sure if I used your proposal correctly, nevertheless "best" result
was following (which leads me again to wrong workflow idea of non existing
body element):
Uncaught TypeError: Cannot call method 'observe' of undefined
What is working for me is jQuery with 10 years old javaScript:
jQuery(document).ready(function() {
document.body.setAttribute("onload","setPosition();");
document.body.setAttribute("onScroll","setPosition();");
});
So, problem solved. Thanks for all answers!
Best regards
Ladislav

You're using JavaScript that looks like 10 years ago. Use event listeners
for that. If you're using Prototype, it would be something like
$$('body')[0].observe('load', setPosition);
$$('body')[0].observe('scroll', setPosition); (this wasn't tested).
