For your testing pleasure, the Robotics Academy has released a new set of beta versions of ROBOTC for various platforms.  So go get your own copy for the NXT right here: [LINK].

Changelog:

  1. Fixed ROBOTC behaviour not to automatically disabled TETRIX motors in a low-voltage situation.
  2. Fixed incorrect “SizeOf” function.
  3. Disabled Bluetooth Debugging information in the “Debug Stream” Window.
  4. Fixed issue with “Registering” when doing a manual activation with ROBOTC.
  5. Added version 1.6 of the Driver Suite.

I haven’t had a chance to install it myself, I will later today.
