I have the following sample code: http://jsfiddle.net/yWe2C/3/
I have an outer div, inside that I have an h3 tag and a paragraph tag. I set up mouseenter and mouseleave events on the outer div. In IE7, (works fine in Firefox), as near as I can tell, because of the margin on the h3 tag, the browser seems to think the mouse is no longer in the outer div when the mouse is over the margin part of the h3 tag. To see this, move your mouse inside the border of the h3 tag. Then move the mouse just outside the border of the h3 tag. Why does the mouseleave event fire in IE7 but not in Firefox when the mouse is over the margin of the h3 tag? I've tried this with 1.2.4, 1.2.5, and 1.3.0 (compat). The behavior is consistent
