Thanks Bob, I may have to take you up on that. Hopefully it will get fixed. I 
did tinker with it a bit and found that if I set the backgroundColor of the 
button to something dark the text shows up, so the issue is the change in 
appearance to the active tab being white - so the default white text  is there, 
just not visible against a white background.
