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/) 334861 1 ap 2011-01-14 22:54:08 -0800 Yes, that's a known issue. This is almost a philosophical question - what does it mean to be online? For example, are you online if you're on intranet without access to Internet? If all one cares about is testing a web app running in a virtual server in VMWare, they want navigator.onLine to return true even if that's the only active interface. *** This bug has been marked as a duplicate of bug 32327 ***
