Macromedia site navigation...delay onRollover?

Not sure if it is just me, but I cannot seem to find any other menu out there that functions like the macromedia menu. I am building a navigation for ford.ca and the client wishes the navigation to behave like the macromedia site. MM site nav has some sort of delay that is triggerred before the rollover function fires, as well it detects when the mouse stops moving before firing. Take a close examination and you will see this. Does anyone know of a tutorial that implements this behaviour? Or if you are confident you know how its done can you shed some light on this? Please don’t post assumptions. I have plenty of my own.

Anyone’s help would be greatly appreciated!
