I downloaded the Google Chrome application called "Offline Google Mail" by Google. I used it a few times (online), it works fine, syncs, whatever.
Yesterday I was on the bus and decided to give a try to Offline GMail in the real world. Except all I got was something like "Web application is not reachable". If I read this correctly, it's complaining that I am offline.
Do I have to be online for Offline to work? What is the point of Offline Gmail then?
