Modifying the _accProps variable has no effect by itself. You must also use the Accessibility.updateProperties method to inform screen reader users of Flash content changes. Calling the method causes Flash Player to re-examine all accessibility properties, update property descriptions for the screen reader, and, if necessary, send events to the screen reader that indicate changes have occurred. When updating accessibility properties of multiple objects at once, include only a single call to Accessiblity.updateProperties (too frequent updates to the screen reader can cause some screen readers to become too verbose). See the Accessibility.updateProperties method in the ActionScript 2.0 Language Reference. Implementing screen reader detection with the Accessibility.isActive() method To create Flash content that behaves in a specific way if a screen reader is active, use the Accessibility.isActive() ActionScript method, which returns a value of true if a screen reader is present, and false otherwise. You can then design your Flash content to perform so that it's compatible with screen reader use (for example, by hiding child elements from the screen reader). For more information, see isActive (Accessibility.isActive method) in ActionScript 2.0 Language Reference.
