Description

Steps to reproduce:
1. Take this code.

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="addChildren()" width="600" height="500">
<mx:Script>
<![CDATA[
import mx.controls.Label;
private function addChildren():void {
for (var i:int = 0; i < 100; i++)

{ var l:Label = new Label(); l.text = "line"; l.width = 50; this.content_vbox.addChild(l); }

}
]]
>
</mx:Script>
<mx:Canvas borderColor="#FFFFFF" backgroundAlpha="1.0" backgroundColor="#FFFFFF" left="10" top="10" right="150" bottom="10">
<mx:VBox height="100%" left="0" top="0" right="0" id="content_vbox">
</mx:VBox>
</mx:Canvas>

</mx:WindowedApplication>

2. Generate an air app
3. Install it on winxp (air 1.5.1)
4. Run the app and scroll down the list
5. minimize the app
6. maximize the app

Actual Results:
The scroll bar is reset to the top.

Expected Results:

The scroll bar appears in the same position when I minimized the app.

Workaround (if any):

Not know. Probably catching the windowActivate event.
