When compiled, the block will now show a padlock symbol in the blocks folder. You must also remember to delete the source code from the project (obviously after having saved it somewhere outside of the project). The block will now be protected and no one can see the code. All they can see is the blocks variables.
	Programming today is the race between software engineers building bigger and better idiot proof programs, and the universe producing bigger and better idiots. So far, the universe is winning...

Click on the check-box in the 'Know-how-protection'-column and after you have created a copy of the unprotected block your block will be protected.
