I could be wrong, but my understanding is that everything in Javascript 
is associated with an object.  In a browser environment, window is the 
top-level object, so all functions and variables that appear to be 
top-level items actually are properties and methods of the window 
object.  If that is true, then

function onmouseover(e) {}  is the same as
window.onmouseover = function(e) {}

So, the behavior you are seeing is the behavior I would have expected.
