Hi there,

I'm a support engineer at VMware and this was reported to us recently.

When addEventListener is listening for "online" or "offline" and Fusion is installed, the function returns True even when it should be False.

http://apollo.mikeroysoft.com/wktest.html  demonstrates the issue pretty clearly.

Script in full:
    <script type="text/javascript" charset="utf-8"> 
        window.addEventListener("online",function() {
            alert("Online");
        },false);

        window.addEventListener("offline",function() {
            alert("Offline");
        },false);
    </script> 

When Fusion is not installed, it behaves as expected.  When you turn Airport off, or unplug ethernet, an alert is raised, and when you re-connect it, a new alert is raised.
When Fusion is installed, nothing happens.

We believe it is detecting our vmnet interfaces and returning a false-positive.  

If you run from Terminal: 

sudo ./boot.sh --stop  

the issue disappears and things behave as expected.  This command shuts down all the Virtual Network interfaces.
(First, cd to: /Library/Application Support/VMware Fusion/)
