> Run the following application. Instructions are included when running the app. Basically, if you open a modal TitleWindow that contains an Alert, closing the Alert popup with the TitleWindow remaining present causes the main application to lose its blur.
> The desired effect is that when a modal TitleWindow is displayed, the main app should always be blurred. 
> The actual effect is that the main application is NOT blurred when a modal TitleWindow is displayed in certain conditions. The condition is if the user opens an Alert from the TitleWindow and closes this Alert popup, and the TitleWindow remains after the Alert popup is closed.

> ------- WORKAROUND --------
> Need to manually re-introduce blur in the main app using something like:
> var myBlurFilter:BlurFilter = new BlurFilter(1.75, 1.75, BitmapFilterQuality.MEDIUM);  
> mx.core.FlexGlobals.topLevelApplication.filters=[myBlurFilter];
> which then needs to be manually removed after closing the TitleWindow using something like:
> mx.core.FlexGlobals.topLevelApplication.filters=null;
> mx.core.FlexGlobals.topLevelApplication.filters=[];
