The "restart your computer" message popped up, and I rescheduled it for 2 hours later.
Well, just the milisecond that I pressed the enter key to go to a new paragraph in what I was writing ONLINE it popped up again! of course it restarted my computer and I was helpless ( I lost a couple of paragraphs. I'm pressed for time so to me 20 minutes of rewriting are important).
Inadvertently shutting down the computer because of this pop up could be bettered by just popping up a "confirm" alert set to "Cancel".
If you don't mind my suggestion.
