Please. A powercycle fixed it and besides, if you don't want people to play with the gear then don't put it in the general public aisle. That's where people will mess with your gear as any trade show booth operator very well knows.
I worked in a computer store, the number of pranks that people got up to with the gear there was insane and some of them were quite a bit more harmful than this one. I really don't see the problem. As long as you can reboot the device no harm done. Once people start flashing your systems or rewriting boot loaders we're in different territory.
Thanks for the link. I have not read that manual for over 40 years. Appendix B "Advanced Display Programming" is where I learned the mischief I did at the show.
I guess I could have prevented a lot of HN grief if I had clarified that a AC power cycle absolutely clears all display memory and completely eradicates anything that I had put there.
