DHTML Window widget (v1.1)

Script URL (on DD):

I'm very interested in the work John Scheuer did on the dhtml window to get it to assume a fixed position on screen. See post:

This works fine in Safari and FF but disappears when window scrolled in IE8 and won't even be dragged and in Opera 11.5 the window shoots to the left when you try to drag it. Can the code be tweaked to get it working in all these 4 browsers?

I'd very much appreciate it.
