Doing the Andes_Coffee tutorial. Having many problems. Double and triple checked that I did everything by the book. If I do an F12 (preview in browser) without being connected to internet I get a " must be connected to the internet, work offline? " window. Click work offline and get page can't be found. Then I connect to the internet through isp and wallah! I can preview my page. Anybody know what gives? tia, Jack
