I am trying to open a url via flex per standard code below, this url will take a long time to load as it creates a large excel file. The problem i am having is right after navigateToRUL() is called, flex hides the hourglass and returns the control of the screen back to the user BUT you can see it's still trying to load the url so the user gets a frozen screen.
How do i lock the screen with the hourglass/loading until the url page is actually completed loading. Thanks
var url:String = "ExcelExport";
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;
request.data = formParams;
