I think if you save the effect reference you could call the cancel
method which I believe would halt the effect at whatever point it was
in its processing and then start a new slide up effect, you'd have to
test that out though.
Also I'd avoid globals at all costs in dealing with effects, as im
sure your menu has multiple pull downs. Try just using properties of
the elements you're effecting, then they'll be scoped within the
element.
