That's good info. I still don't understand why it works fine with the default Dashboard vs the C++ dashboard. My guess is the RoboRio is transporting the exact same stream to the Driver Station in either case, and for some reason using the C++ dashboard it fails.

I asked in another thread if anyone could explain what the difference is between the C++ dashboard and default dashboard, and no one can explain that, either.
