Sprite Image Size Problem

I am writing some test cases for our Actions wrapper classes using the images from the TestCpp project. My sprites are displaying at half the size that they do in the cocos2d-x test suite. So in this simple test program:

@ CCScene* scene = CCScene::create();// FluxScene::createWithFile(“SpriteSizeTest.lua”);
CCSprite* pSprite = CCSprite::create(“TestResources/Images/grossini.png”);
pSprite~~>setPosition);
scene~~>addChild(pSprite, 1);
pDirector->runWithScene((CCScene*)scene);
@

My sprites end up half the size that they do in the Action Tests in the TestCpp project. Is the test project doing something that makes the sprites bigger? Or am I doing something wrong?

I took a look at the scales of the scenes and sprites in the debugger and they were all 1. I also couldn’t really see any difference in the transforms.

This is running in the iPhone4 Retina iOS 7 Simulator, BTW.
Thanks,
