Dear Aren,
I ask you this problem because I never found a solution.
As you know, usually an Android tablet (also smartphone) is 1280 * 800 ...
BUT! there is inside the screen the cursed

system bar that use a lot of pixel (on 1280*800 is 64px so height is 736)
Now, rightly NGUI check for Screen.height and the result is 800 instead of 736. This problem hits everytime I use a draggable panel on the bottom anchor from left to right corner that cover the entire width (800px). In this case the draggable panel is scaled not correctly and everytime I need to setup UIRoot in 736 manually ...
Any solution?
