Trying to click on the stop execution tab with a mouse while a drive chain is chewing up a student is not acceptable. How is a total compact rio shut down handled? I have not seen any thing yet that leads me to believe that this issue is well handled. Please NI and beta teams tell me I have nothing to worry about.

Also note that there does not appear to be any fuse between the battery and the victors in the video. Sloppy.

This issue is handled through the competition port on the DS(Drivers Station)
There are 2 commands that disable the robot. the Disable command and the E-stop.
when the cRio receives the disable command, the outputs are temporarily disabled, and can be re-enabled again.

When the cRio receives the E-Stop command, all the outputs are disabled until the cRio is rebooted.
