v1.9.1 Fix for incorrect window display mode on some phones.
v1.9 Fixed display for high resolution phones (Evo 3D, Sensation, Atrix, Droid 3 etc). Also fixed for tablets with 1024x600 display or higher. On tablets greater than 7 inches the app is displayed in a pop-up window to avoid having monster-sized buttons! Added Area conversions. Fixed bug in dividing percentages.
