0. First of all, you can't assume it is a he, we can't assume gender in 2018.
1. Secondly, it's a technical question, not a programming question. The user did not ask how to write code to prevent cross page posting or how to code to DO cross page posting. The OP simply asked what it was.
In fact, if the rest of you would READ the rules at the top, it clearly states "Technical discussions are encouraged"
Everyone is born right handed. Only the strongest overcome it.
My daughter wanted/got an akai Miki ii mini midi input device for Christmas, so I ended up sitting with her trying to up date the firmware as it just was having none of it. God their software is crap.
Anyway, the daughter had setup shop on the floor, as they do, so we were sat there and the dog had decided it wanted in on the action and proceeded to barge in and stand with front paws on the laptop keyboard.
It was like slow motion! She wandered in, paws connected, the screen displayed a whole bunch of artifacts, then went completely haywire, followed by a BSOD, but only a poor rendition of the sad face part on the top left.
Forced reboot, and I had visions of the laptop being dead, the motherboard being shorted out by the weight of a dog.
Fortunately it appears to have survived. Yes both the laptop and the dog!
