Rollover - the rollOUT part

Hey All:

Ive been using the typical way for rollovers and the rollout like in the tutorial found on this site (

However, its always bothered me a bit in terms of the RollOut part of the animation. When you move the cursor/mouse quickly across multiple items, the ‘Play’ rollout part stops suddenly and does not finish.

How can you make sure the rollout play all the way through no matter what.
I guess also, if u move the cursor/mouse away before the entire RollOver finishes, it’ll just start the RollOut…

Sorta like on the main nav of:

I hope this makes sense…
Any help or ideas is greatly appreciated!
