How can one get VoiceOver in Mac OS X 10.5 (Leopard) to work with third party applications such as Microsoft Office or Mozilla Firefox? VoiceOver works great with integrated applications such as Safari or TextEdit. The user is able to type words and/or characters in Safari or TextEdit and VoiceOver will read the words and/or characters to the user. However, in third party applications, VoiceOver does not read the typed text. Any ideas? User would prefer not having to purchase software to add this capability. Thanks!
