Hi, Minor concern re fullScreenWidth and fullScreenHeight as I believe the height doesn't include system toolbars - not sure if that happens on iOS or not.
Looking at this: http://www.adobe.com/devnet/air/articles/multiple-screen-sizes.html It states: Unfortunately devices often report the wrong dpi (notably for iOS displays). Capabilities.screenDPI is actually a best guess based on other information, but it may also be wrong. For comparison, you can get the original dpi reported by the operating system as follows: var serverString:String = unescape(Capabilities.serverString); var reportedDpi:Number = Number(serverString.split("&DP=", 2)[1]); Thanks, Justin
