[AC-1351] ANDROID: After adding 3 windows on top of each other, i get a black screen

I pop windows on the screen with this code function NavigationController(a){ // this is to avoid errors a = a || {}; a.window = a.window || Ti.UI.createWindow({ layout:'vertical' }); // this is to handle the iPhone Nav functionality var Android = true; // there is no Nav in Android, so let's return the window if(Android){ a.window.push = function(b){ b.open({ fullscreen:true, }); }; return a.window; } } Programmatically or using the back button on the 3rd window...i always get a BLACK screen...and it requires me to hit the back button again for my app to appear with window 2....
