Full Screen Error

Hi. Just started with MoSync and i was testing my app on my android to see how it looks, looked great.

However i then used maScreenSetFullscreen(1) to make it full screen, now all i get is a black screen. I've attached the cpp and h for anyone who wants to take a look at what i did in detail but basically...

MyMoblet::MyMoblet() {
Engine& engine = Engine::getSingleton();
maScreenStateEventsOn();
maScreenSetOrientation(SCREEN_ORIENTATION_PORTRAIT); //orientation
maScreenSetFullscreen(1);//Make full screen

MAExtent screenSize = maGetScrSize();
scrWidth = EXTENT_X(screenSize);
scrHeight = EXTENT_Y(screenSize);

mainScreen = new MainScreen();
mainScreen->show();

}

extern "C" int MAMain() {
moblet = new MyMoblet();
MyMoblet::run(moblet);
return 0;
}

this is the crux of what i did, with an image in my main screen to display. Works fine is maScreenSetFullScreen(0) is used, but not full screen.

Any help appreciated.

Kyle.

PS: Didn't know if this was for the bug section of the forum or tutorial, as i'm new i went for tutorial.
