You must not be working with JavaScript or Master Pages (or if you are, you're using Microsoft AJAX). Create a master page, then create a placeholder or panel in a content area, then put a textbox in it and refer to it by its generated HTML ID attribute (it's probably something like ctl00_MainContent_Panel1_MyTextBox at this point) in a javascript. Then if you move it to another panel, the ID changes. That's the mangling he's describing and it is by far the biggest issue I have with an otherwise solid framework.
