Events registered on img objects don't fire if the image has an associated image map, and the targeted part of the image is part of an area. NOTE: Events only fire in MSIE 6. They do not fire in Opera 9 (Windows/Mac), Firefox 1.5 (Windows/Mac) or Safari 2. Reported on 20 September 2006. Test page: http://joynt.net/steve/imgmap/maptest.html Tested on locally-built debug build of WebKit r18399 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).

I think this is actually correct behavior and a bug in IE. We might reconsider if there are real sites depending on the IE bug.
