Default.png very STRANGE

Getting Started Newbie Questions

Hi
I’am using director class but I think it’s not a problem.
My main.lua look like this :

display.setStatusBar(display.HiddenStatusBar)  
local default = display.newImage("Default1.png")  
default.alpha = 0  
local director = require("director")  
local mainGroup = display.newGroup()  
  
local function main()  
 mainGroup:insert(director.directorView)  
  
 director:changeScene("loadingmenu")  
 return true  
end  
  
transition.to(default, {time=5000, alpha=1 , onComplete = main})  
timer.performWithDelay(5050, function() default:removeSelf(); end, 1)

Every thing is ok on Corona simulator but when I compile the game the Default.png first display in Portrait mode with bad resolution and then in Landscape mode.
It’s look like Default.png in Portrait mode is displaying before (???) Corona files lunch . [import]uid: 13156 topic_id: 6922 reply_id: 306922[/import]
