The following code results in the button being displayed roughly 25% of the way down the screen and 1/2 cut off. I would expect it to display at the very top of the window?
#constant deviceWidth = 768
#constant deviceHeight = 1024
SetWindowSize(deviceWidth, deviceHeight, 0)
#constant BLANK_BUTTON 3
global button_blank_up
global button_blank_down
button_blank_up = LoadImage("button_blank_up.png")
button_blank_down = LoadImage("button_blank_down.png")
AddVirtualButton( BLANK_BUTTON, 50, 0, 50)
SetVirtualButtonImageUp( BLANK_BUTTON, button_blank_up )
SetVirtualButtonImageDown( BLANK_BUTTON, button_blank_down )
