• To check you have your tabs set up correctly, would it be possible to show us the code of your app.js file which creates your tabs, then I'm sure one of us might be able to help.

• The tab setup is basically cribbed from the Kitchen Sink. I put it into a function 'cuz there are a couple of asynchronous processes that have to run before the opening window can be displayed. Here's the relevant portion:

  function launchApp(tzData) {
      var tabGroup = Titanium.UI.createTabGroup();
  
      //*** The 'Hours' window is the root
      var hoursWin = Titanium.UI.createWindow({  
          title: 'The Hours',
          url: 'main_windows/planetary_hours.js',
          backgroundColor: 'black',
          barColor: '#111',
           latitude: tzData.latitude,
           longitude: tzData.longitude,
           tzOffset: tzData.offset,
           currentDate: null
      });
      var hoursTab = Titanium.UI.createTab({  
          icon: './images/hours.png',
          title: 'Hours',
          window: hoursWin
      });
  
      //*** Set Location page
      var locWin = Titanium.UI.createWindow({  
          title: 'Set Location',
          url: 'main_windows/set_location.js',
          backgroundColor: 'black',
          barColor: '#111',
           latitude: tzData.latitude,
           longitude: tzData.longitude
      });
      var locationTab = Titanium.UI.createTab({  
          icon: './images/loc_change.png',
          title: 'Location',
          window: locWin
      });
  
      //*** Set Date page
      var dateWin = Titanium.UI.createWindow({  
          title: 'Set Date',
          url: 'main_windows/select_date.js',
          backgroundColor: '#fff',
          barColor: '#111'
      });
      var dateTab = Titanium.UI.createTab({  
          icon: './images/date_change.png',
          title: 'Date',
          window: dateWin
      });
  
      //*** Settings page
      var settingsWin = Titanium.UI.createWindow({  
          title: 'Settings',
          url: 'main_windows/settings.js',
          backgroundColor: '#fff',
          barColor: '#111'
      });
      var settingsTab = Titanium.UI.createTab({  
          icon: './images/settings.png',
          title: 'Settings',
          window: settingsWin
      });
  
      //*** Page selection tabs
      tabGroup.addTab(hoursTab);  
      tabGroup.addTab(locationTab);  
      tabGroup.addTab(dateTab);  
      tabGroup.addTab(settingsTab);  
  
      //*** Open the tab group
      tabGroup.open();
  }
