I have a fairly complex asp.net page based on UpdatePanels and jQuery UI. Unfortunately, when the panels update, the jQuery UI widgets leak memory like crazy in ie7, even if I manually 'destroy' them. Does anyone know a technique/patch to prevent these leaks? I've created a simple example page with a slider inside an UpdatePanel. Just click the 'Leak' button and refresh the page to see the leak in sieve.
