New IFace...Opinion needed

I just made a new interface for my website. Some of the rollovers take a little time to work when you move your mouse over them and I on't know why but trust me, they will work. Anyway, heres the link.....

Can anyone tell me how to make the mouseovers happen without waiting? I'm not sure why it's doing it.

pretty nice, hard to say when it's just the header thingy...

About the mouseOvers...
You should do a preload :

script language="JScript"
image0 = new Image()
image0.src="images/mouse_over_image1.gif"

image1 = new Image()
image1.src="images/mouse_over_image2.gif"

image2 = new Image()
image2.src="images/mouse_over_image3.gif"
/script

...and so on...
sorry not sure how to show code here...
So you should put <> on script language and /script
