Yes! That's the problem! After reading through the thread I changed my code to set cacheAsBitmap=false on the instance of the PopUpWindow rather than in the MXML component definition. In other words, this:
var crRTEW:ContentRowRTEWindow = ContentRowRTEWindow(PopUpManager.createPopUp(this, ContentRowRTEWindow)); crRTEW.cacheAsBitmap = false; And NOT this: <mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:v="views.*" cacheAsBitmap=false ... > Problem solved!
