You can try using the <code>callLater()</code> method to delay the Alert slightly: <pre lang="mxml"> <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[ import mx.controls.Alert; protected function onFocOut():void { Alert.show("IS THIS ALERT MODAL ?"); } ]]> </mx:Script> <mx:TextInput focusOut="callLater(onFocOut);"/> <mx:TextInput/> </mx:Application> </pre> Peter @Sankara narayanan,

How to make a alert truly(?!) modal? That is user should not be able to type any thing in the field which has the current focus , while the alert is being thrown. <pre lang="mxml"> <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[ import mx.controls.Alert; ]]> </mx:Script> <mx:TextInput focusOut="Alert.show('IS THIS ALERT MODAL ?');"/> <mx:TextInput/> </mx:Application> </pre> In this if we are changing the focus from field1 to field2, The alert is thrown.But the user can type things in field2. How to do prevent this? Thanks in advance. Hi peter,
I have one doubt.
How to make a alert truly(?!) modal?
That is user should not be able to type any thing in the field which has the current focus , while the alert is being thrown.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">
 
    <mx:Script>
        <![CDATA[
            import mx.controls.Alert;
        ]]>
    </mx:Script>
 
    <mx:TextInput focusOut="Alert.show('IS THIS ALERT MODAL ?');"/>
    <mx:TextInput/>
 
</mx:Application>

In this if we are changing the focus from field1 to field2,
The alert is thrown.But the user can type things in field2.
How to do prevent this? Thanks in advance.
