Above image is a screen shot of a problem with a test implementation.
I am using yui-ext for making a nested layout..

[main layout]
north
center 'Drag target'
east
[east layout -nested]
-- center 'Toolbox'
-- south 'Properties'
south

My toolbox is loaded with controls that i drag and drop to create webparts on the droptarget.
things are working.. but when i drag the tool outside the toolbox or outside yui-ext layout (as shown), either to the right, or to the bottom... the layout resizes and starts shivering.

any suggestions to solve this problem ?
i am using YAHOO.utils.DragDrop.. and related namespace
also.. i have the main layout itself inside a big iframe (this was since i understood yui-ext layouts always assume all width and height on page unless inside a dialog)

thanks,
Harish.
