javascript/chrome onunload issue

Code:

---

        var win = window.open(page,'window','width=270, height=155, left=300, top=200');
   
        alert('1');
        win.onunload = function()
        {       
            alert('2');           
        }

---

Consider the above code:


In firefox, I see the new window popup, get a '1' alert, then close the popup window, then see the '2' alert.

In chrome, I see the new window popup, get a '1' alert, then additionally get the '2' alert immediately following the '1'.
When I close the chrome window I get no alerts.

What is the reason for this and how can I resolve this issue?

Remember that they have two separate JavaScript engines. In my version of Firefox, the second alert does not fire. What version of Firefox are you running?
