This is just an FYI. If you ever got this fatal error: Error #1009: Cannot access a property or method of a null object reference. at flash.html::HTMLLoader/onLeftMouseUp()
...then it might be useful to know that I just logged this AIR bug[1] about it. Of course, any suggestions on how to better describe it are welcome. I will also post a reply when I implement a workaround in FlexHTMLLoader. Thanks. [1] https://bugbase.adobe.com/index.cfm?event=bug&id=3925672
