Jeromy Evans commented on WW-2180:
----------------------------------

This seems to relate to a known bug in IE6. When a node is removed from the DOM 
IE does not remove the event listeners.  The linger forever and can result in 
massive memory leaks.

I couldn't find the authoritative source at MSDN, but here's a reference: 
http://www.quirksmode.org/blog/archives/2005/08/addevent_consid.html

It is almost certainly a Dojo issue, not a Struts issue, as dojo performs the 
DOM updates and is responsible for working-around the many, many, many, many, 
many, many, many, many IE6 bugs that will never be fixed.

I'd like to propose an "international upgrade IE6 day", where every website 
that detects that user-agent on the day redirects the user to an informative 
upgrade and alternatives page.
