I guess it can be done with something like this... haven''t tested it
though, so I''m not sure if it does work.
var t;
$$(''a.info'').invoke(''observe'',
''mouseover'', function(ev) {
t = updateDiv().delay(1);
});
$$(''a.info'').invoke(''observe'',
''mouseout'', function(ev) {
window.clearTimeout(t);
});
