That's not completely certain. Many Web pages use a function that abstracts the difference between addEventListener and attachEvent, so it's possible that there are existing Web pages which add a "focusin" handler with addEventListener in non-IE browsers, but behave properly because it is never dispatched. I don't know whether such pages actually exist, but I would not be so quick to rule it out. Regards, Maciej
