Text to speech nonfunctional in standalone

[Marian Petrides]

I just put together a very simple demonstration of the RevSpeak command 
which consists of a card with 2 items on it:

A field named "TextToSpeak" into which one enters text  and a button 
containing the following simple script.

On mouseUp
   Put field "TextToSpeak" into whatText
   RevSpeak whatText
end mouseUp

This works just fine (speaks the text entered into the field whenever 
button is pressed) in the IDE running in Mac OS X 10.3.  However, when 
I make the stack into a standalone for OS X, pressing the button yields 
nothing but silence.

Anybody have any thoughts on why this works in IDE but not in 
standalone???

Thanks

Marian
