Found this today working with an early 600 build, downloaded 617, still happening:
local box = display.newRect(0,0,768,1024);
Launch the simulator - see a blank “device”. Re-launch, sometimes the box shows, sometimes not. About 50/50. Problem exists across all “devices”. [import]uid: 64596 topic_id: 14954 reply_id: 314954[/import]
