Failed Alert window when application loaded from SWFLoader

Question

For example i've created two simple application.
Parent application must to load another child application
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
               creationPolicy="all">
    <mx:SWFLoader id="subApp1" trustContent="true" source="../subapp/Subapp.swf"/>   
</s:Application>
In child application i only call Alert.show in button click event.
Subapp.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
               pageTitle="Subapplication"
               xmlns:ns1="*" width="600" height="1000"
               creationPolicy="all">
    <s:Button id="btnAlert" label="Alert" click="Alert.show('test mess', 'Title')"/>
</s:Application>
As a result we receive an Alert-window displaced upwards of a window of a browser.
Screenshot:
Instead of a usual window which is normally displayed if child application to call directly
Screenshot:
The problem can be solved if i specify parent object for Alert call
<s:Button id="btnAlert" label="Alert" click="Alert.show('test mess', 'Title', Alert.OK, this)"/>
But it is not the desirable decision as the real child application very big.
Somebody worked with this sort of problems?
How it probably to solve?
Thank you very mach!

Harbs,
Things are getting weird here...
This is a crop of the GUI in Halo:
and this is what the CS Extension Builder theme looks like:
There's no more the vertical separator *nor* the arrow in the combobox! Let alone that the plus button has gotten a crazy size.
Uhm... it seems like there's something wrong.
And by the way, no matter what theme I chose, my Design tab always shows the bluish GUI:
Being Halo, shouldn't it be gray? Why on earth it's grayish blue to me?!
I've had some random warnings, not specifically in this project, like:
"Design mode: Cannot load CSXSLibrary-2.0-sdk-3.4-public.swc (reason: ERROR: Load Verify). It may require classes (such as Adobe AIR components) that are not supported by design mode. Check the Eclipse error log for more details. main.mxml /01/src Unknown Problem"
I'm wondering whether FB has some troubles with the preferences...
Could someone please test whether the change in theme leads to these dramatic changes in appearance?
Is it correct that the default appearance is this (bluish) one?
Thanks,
Davide
