Apycom jquery menu

Apycom jquery menu

Hi all.....
I'm using the apycom jquery menu style 1 (dim grey) http://apycom.com/menus/1-dim-gray.html
It's a great looking menu but does anyone know how to 'delay' the dropdown menu closure when your mouse moves off of it?
I can change the speed of the menu opening and closing, but not can't find a way to delay.
It's too easy for visitors to 'slip' off the menu and if you have two child menu's, it get frustraing if you drill down to the secon child menu and slip off. You have to go back to the top menu and start again.
 
Any ideas from you clever peeps??
 
Regards
Andy
