Be sure to open the other boxes to get a good idea of how they interact.
These boxes have a set width, but are using Floatbox's ability to measure content and auto-size the height appropriately.
They also have disableScroll:true set so that you can scroll the underlying page without having the floatboxes move off screen.
(Like many things, this doesn't work in IE6.)
Go ahead and drag these boxes around by their frames,
resize them, move different ones to the front and close them in any order.
You can open other stuff from the underlying page as well.
