But basically I dont get what you want...
onmouseover="window.status='http://www.whatever.com/'; return true;"
onmouseout="window.status=''; return true;"
this code makes sure
http://www.whatever.com/ will show up every time you are "OVER" the item (whtever item it is) and whenever you leave this object it empties the status line.
What do you want to do?
