Fixed.

in 1.4.1 release

$("#node").live("hover", function(e) {alert(e.type)}) fires two events: mouseenter and mouseleave, like $("#node").hover(function(e) {alert(e.type)})

but in 1.4.2 release

$("#node").live("hover", function(e) {alert(e.type)}) fires two events: mouseover and mouseout, but

$("#node").hover(function(e) {alert(e.type)}) still works as expected - fires mouseenter and mouseleave.

Tested in FF3.6, Safari 4

Nope, that's very much intentional - we made it that way so that it was possible to bind one function that could handle both events.
