Ok, I found a solution to my issue.  I have to use a Nodecallback in order to 
make this work in a composite viewer.  I was originally modifying the alpha 
value of the text in my main loop after each frame() call.

This worked great with the osg::Viewer, but did not using the Composite viewer. 
 

I modified the code at the following link and it worked great for me:

Cheers,
