N.B. The bug with closures is associated with a problem in a single use case with IE6's garbage collector, and Microsoft patched it two-and-a-half years ago. Are you sure about that? From what I understood they couldn't patch it because some major unnamed web sites actually relied on DOM elements not being cleaned up to work properly. http://blogs.msdn.com/b/ericlippert/archive/2003/09/17/53028.aspx http://blogs.msdn.com/b/ericlippert/archive/2003/09/17/53028... As of IE 7, I remember I still had to close out memory leaks on some code that was binding an event to a DOM node.
