Mihai Chira commented on FLEX-26478:
------------------------------------

I tried this (with pasting a lot of text, starting to drag it up, pressing ALT+TAB), and couldn't reproduce with SDK 4.13:

{code}
<?xml version="1.0"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                       xmlns:s="library://ns.adobe.com/flex/spark"
                       applicationDeactivate="rollOutHandler(event)">

    <fx:Script><![CDATA[
        import mx.events.AIREvent;

        private function rollOutHandler(event:AIREvent):void
        {
            if(input.parent)
                removeElement(input);
        }
        ]]></fx:Script>
    <s:TextArea id="input" width="200" height="200"/>
</s:WindowedApplication>
{code}
