I am trying to make Mikes IFrame Demo
http://www.cross-browser.com/cbe/examples/iframe1.html resizable
http://norbu-verlag.de/Norbu/Buecher2.php
I tryed this, but it is wrong.

But I haven't got any idea of the target of the IFrame
function dragListener(e) {
if (e.cbeCurrentTarget.isResizing){ e.cbeCurrentTarget.resizeBy(e.dx, e.dy);

var mm = e.cbeCurrentTarget.secondChild.mm;
mm.resizeBy(e.dx, e.dy);
}
}
