could use some quick javascript help!

I downloaded this great free script that creates a cascading menu for
websites. You can see it working here:

http://www.solarbus.org/pfe/index-2.shtml

The one thing I don't like about it, is once you mouse over the menu bar,
and the cascading part appears, it all stays in view unless you click on a
menu item, or click outside the menu to make it disappear.

I am sure I have seen similar cascading menus like this, where the menu
disappears when your mouse leaves the menu (without clicking). It might
happen after 5 seconds or so of the mouse being off the menu, or even
immediately after the mouse leaves the menu. Either would be fine.

Can anyone here suggest some code I can add to the javascript that will make
this happen?

Here is the javascript code, which is in an external .js file. It's not
very long:

function InitMenu()
{
var bar = menuBar.children

for(var i=0;i < bar.length;i++)
{
var menu=eval(bar[i].menu)
menu.style.visibility = "hidden"
bar[i].onmouseover = new Function("ShowMenu("+bar[i].id+")")
var Items = menu.children
for(var j=0; j<Items.length; j++)
{
var menuItem = eval(Items[j].id)

if(menuItem.menu != null)
{
menuItem.innerHTML += "<Span Id="+menuItem.id+"_Arrow
class='Arrow'>4</Span>"
//var tmp = eval(menuItem.id+"_Arrow")
// tmp.style.pixelLeft =
menu.getBoundingClientRect().Right //- tmp.offsetWidth - 15
FindSubMenu(menuItem.menu)}

if(menuItem.cmd != null)
{
menuItem.onclick = new Function("Do("+menuItem.id+")") }

menuItem.onmouseover = new
Function("highlight("+Items[j].id+")")

}

}
}
function FindSubMenu(subMenu)
{
var menu=eval(subMenu)
var Items = menu.children
for(var j=0; j<Items.length; j++)
{
menu.style.visibility = "hidden"
var menuItem = eval(Items[j].id)


if(menuItem.menu!= null)
{
menuItem.innerHTML += "<Span Id="+menuItem.id+"_Arrow
class='Arrow'>4</Span>"
// var tmp = eval(menuItem.id+"_Arrow")
//tmp.style.pixelLeft = 35
//menuItem.getBoundingClientRect().right - tmp.offsetWidth - 15
FindSubMenu(menuItem.menu)
}

if(menuItem.cmd != null)
{
menuItem.onclick = new Function("Do("+menuItem.id+")") }

menuItem.onmouseover = new
Function("highlight("+Items[j].id+")")

}
}
function ShowMenu(obj)
{
HideMenu(menuBar)
var menu = eval(obj.menu)
var bar = eval(obj.id)
bar.className="barOver"
menu.style.visibility = "visible"
menu.style.pixelTop = obj.getBoundingClientRect().top +
obj.offsetHeight + Bdy.scrollTop
menu.style.pixelLeft = obj.getBoundingClientRect().left +
Bdy.scrollLeft
}

function highlight(obj)
{
var PElement = eval(obj.parentElement.id)
if(PElement.hasChildNodes() == true)
{ var Elements = PElement.children
for(var i=0;i<Elements.length;i++)
{
TE = eval(Elements[i].id)
TE.className = "menuItem"
}
}
obj.className="ItemMouseOver"
window.defaultStatus = obj.title
ShowSubMenu(obj)
}

function Do(obj)
{
var cmd = eval(obj).cmd
window.navigate(cmd)

}

function HideMenu(obj)
{
if(obj.hasChildNodes()==true)
{
var child = obj.children

for(var j =0;j<child.length;j++)
{
if (child[j].className=="barOver")
{var bar = eval(child[j].id)
bar.className="Bar"}

if(child[j].menu != null)
{
var childMenu = eval(child[j].menu)
if(childMenu.hasChildNodes()==true)
HideMenu(childMenu)

childMenu.style.visibility = "hidden"
}
}

}
}
function ShowSubMenu(obj)
{
PMenu = eval(obj.parentElement.id)
HideMenu(PMenu)
if(obj.menu != null)
{
var menu = eval(obj.menu)
menu.style.visibility = "visible"
menu.style.pixelTop = obj.getBoundingClientRect().top + Bdy.scrollTop
menu.style.pixelLeft = obj.getBoundingClientRect().right +
Bdy.scrollLeft
if(menu.getBoundingClientRect().right > window.screen.availWidth )
menu.style.pixelLeft = obj.getBoundingClientRect().left -
menu.offsetWidth
}
}



The other two parts of the menu are the CSS settings and the HTML code. I
can post them here too if it would help.

If anyone can help me with this, I'd be so grateful!
