Safari big mess

Hello,

first thanks for this easy to use module, it made my life much more easier, really.

my problem is that the module don't work well on (Safari for MAC - Safari for windows), it work so nice on other all browsers, but on safari the menu is not collapsed, all the menu and its sub are displayed by default.

my menu is horizontal menu and have lot of drop down stuff (only one level), please review my screenshot, it has a screenshot for safari and the other for firefox which work so well.
