Dynamic Image Resolution: Why is my image bleeding off the right of the iPad screen?

For Dynamic Image Resolution I have two images named:

Background.png (320 x 480)
Background@2x.png (640 x 960)

My config.lua is:

application =  
{  
 content =  
 {  
 width = 320,  
 height = 480,  
 scale = "letterbox",  
 imageSuffix =  
 {  
 ["@2x"] = 2,   
 },  
 },  
}

In main() I do this:

 playfield = display.newImageRect(Background.png, 320, 480)

The image is displayed correctly on the iPhone and iPhone 4 as you can see: The 320x480 version has one yellow dot in the upper-left corner and the 640x960 (@2x) version has two yellow dots in the upper-left corner.

But on the iPad the correct 640x960 (two yellow dots) is displayed BUT it bleeds (repeats) to the right off the right edge of the image.

The iPad resoution is 768x 1024, which is not an upscaling of the iPhone 4’s resolution by 2x like the iPhone 3 to iPhone 4. That is why you are having the alignment issue, IMO. I am researching this topic myself so I don’t have an answer. If you have figured it out, please post.
