Hi,
I am having a really strange issue with an individual student account. We are trying to write a basic blink sketch from his account, and the sketch verifies and then writes to the board. The sketch does not operate as expected (in this case to make LED blink). If I try to run the same sketch from my account on the same laptop with the same Uno board, it works exactly as expected. I had him make a new account and run it from the new account, and it worked there too.
His old user name was: cesarlopez9983
