Checking mouse leaves window

I don't think there is an event for when the mouse leave the browser that you can capture. Why is it an issue? Maybe there is another solution.

When the mouse is out of all 3 objects, the mosue over effect is terminated.

On what event are you currently triggering this?

if(document.all){document.onmousemove=ocmie}
if(typeof(document.addEventListener)=="function")
{document.addEventListener("mousemove",ocmmoz,true)}

So standard different handlers for Mozilla or MSIE similar browsers

The event handler checks 3 rectangles for the mouse.

OVERLAY BRIDGE
OVERLAY BRIDGE MENU
OVERLAY BRIDGE
OVERLAY
OVERLAY
OVERLAY

The menu point which activates the effect, a bridge to the overlay, to move the mosue to the overlay and the overlay obejct

When the mouse is out of all 3 objects, the mosue over effect is terminated.

Have you tried attaching to the onmouseout event?

Just tried

document.body.onmouseout=alert("HALLO");

error: not implemented

How would you implement mouseout for the body?
