I'm in the middle of a Hype training session and there's a problem on one of my trainees computer.
The Preview in browser function doesn't work. I mean, when you press the icon, click on the dropdown menu, use the real menu, or use a shortcut: it doesn't do anything. Not even open the browsers. He's forced to export to test his animation, and that's not very convenient!…
I got rid of the plist preference file, restarted everything, changed the system default browser…
FYI macOS 10.11.3 + Hype 3.6.3 (584).
