I've had the same bug for iPad 1 when trying to load some a css at runtime by converting it into a SWF file. e.g. if(this.width>500) {      styleManager.loadStyleDeclarations("assets/styleTablet.swf"); } /* CSS file */ @namespace s "library://ns.adobe.com/flex/spark"; @media (application-dpi: 160) {      global      {           fontSize: 24;      }      .introtext      {           fontSize:28;      } } Works fine in the emulator but no images show up in the ad-hoc build If someone either has a solution for this or another solution for changing font size by width rather than just dpi I would be happy with that too.
