Hi!
After updating the core to 1.4.2 today I noticed that the .live('change') stopped firing in Internet Explorer. This was not the case in Jquery 1.4.1, as it was fixed in that version according to this: http://groups.google.com/group/jquery-dev/browse_thread/thread/e74de6015020d160 . I can not see any errors thrown that would stop JS from executing as the rest of the application is working, but as I said, change does not fire. I thought this would be a good thing to take a look at before 1.4.2 is officially released.
