Screen readers do not read all accessibility properties

PowerBuilder follows the Microsoft Active Accessibility (MSAA) guidelines described in Server Guidelines. However, many screen readers do not follow the Microsoft guidelines for clients. As a result, some screen readers read a control’s name and value instead of its AccessibleName and AccessibleDescription. In addition, screen readers that call the AccessibleObjectFromWindow function to obtain an IAccessible interface cannot read accessibility properties in a DataWindow. For more information about MSAA, see the Technical Overview. [CR 393976]
