Spry Fade effect as menu

Hi there.

I'm using the Spry fade effects to show/hide a sub menu. It kind of works
except to get the menu to collape/fade away I have to mouse over the link that
fades the menu in .. It's probably a lot easier to see than to explain so
here's a link to the development page.

If anyone could point me in the right direction with getting this to work
correctly that'd be great.
