Help

Hello,
I made a website which includes an interactive button bar.

the bar arrows (as seen in the picture) follows the mouse (only on the x axis).

I made it a little bit more complicated so that whenever you press on a button and leave the buttonbar area - the arrows come back to the area of the button which was last pressed.

my web is seperated into two parts:
the Head (which contains the button bar) and the Main part which changes according to the buttons in the Head part.

The problem is that whenever i get above the button bar area - the arrows come back to the last button pressed.
but! when i go below the buttonbar zone which is the Main area - it doesnt do anything.

what can i do?
