Without spending too much time at this, I find that it looks as though
that plug-in used the implementation of hover internally rather than
just relying on its public interface. When the implementation
changed, that plug-in wouldn't work.
In the 1.2.1 version of jQuery, hover used mouseover and mouseout
events with some additional logic to ensure that these events weren't
happening when the mouse entered a sub-element. In 1.3.2, that logic
has been encapsulated elsewhere, and hover uses mouseenter and
mouseleave.
If your fix works for you, that's fine. I think a better one would be
to replace jdMenu's use in addEvents(ul) of
$('> li', ul).
hover((hoverOverLI, hoveIOutLI) // ...
with
$(('> li', ul).
.mouseenter(hoverOverLI)
.mouseleave(hoverOutLI) // ...
and the equivalent for the unbinding in removeEvents(ul).
This is not a bug in hover, just a changed implementation, which the
plug-in was depending upon.
