Hi,

I just can’t find the reason why the width and height parameter in the SDL\_CreateWindow function gets ignored if I run my SDL application on the iPhone4.

I use the following code but the device opens always in 320x480 screen mode:

Code:  
SDL\_Window \*window = SDL\_CreateWindow(0, 0, 0, 640, 960, SDL\_WINDOW\_OPENGL | SDL\_WINDOW\_BORDERLESS | SDL\_WINDOW\_SHOWN);

The same happens on the iPad. Did I miss anything?

Thanks for your help!
