I suspect your problem with your home button is caused by some relative or absolutely positioned blocks which are overlaying on top of the menu.
I guess my instructions about the functions weren’t very clear then. What I was meaning, was that the old functions which came with the original version of the plugin will (should) still work. To upgrade from one of the original versions you may need to change the function in your theme. If you aren’t using suckerfish1(), suckerfish2(), suckerfish3() etc. then don’t worry as you can edit all of the same things via the new admin page. I’ll try to improve that chunk of text for the next version.
And nope, that version is the latest so should (in theory) work best.
