Carl's browser window in Facebook goes black and he gets a warning saying to expand his browser window. It happens in both browsers, even if he clicks on full screen icon. What gives? Leo says that the chatroom says that Facebook can cause that. They suggest using the fullscreen option within Facebook.
Mike always ends up in Internet Explorer when using Excel, even though Google Chrome is his default browser. Leo says there may be a setting within Excel, or in the file association database, that's associating with Explorer. Leo suggests going into the control panel and look in there. He may be able to change it in the settings.
