Has anyone else had trouble with the resizing of PNG graphics when they are pulled into the simulator? I’ve been exporting my graphics from Illustrator at 163 ppi since that’s the screen resolution for the iPhone, but when we bring them into the resources folder in the XCode project, some of them double in size.

For example, I made a custom nav bar icon and set the size to 20 x 20. But, when imported, it displays at 45 x 45. Anyone have any ideas here?
