Without going too much into detail, I noticed that all of the browsers (Safari, Chrome, Firefox) stopped supporting timeline features such as "mouse over" action to continue timeline a new timeline (essentially on hover) when previewing Hype project. I couldn't understand why it was happening so I restarted/quit all browsers and hype which didn't help and btw, it also effected projects html files that were hosted.
Finally, I restarted my Mac and everything started working accordingly. Has anyone experienced this?
Did you notice if there were mouse over issues with other parts of applications, like hovering over tabs not getting new colors, etc? (Or hover overs in other web pages not working correctly?)
It sounds like the window server was not sending mouse events to various apps.
I should say this is just a guess, since it seemed that disparate apps were behaving in the same way, indicating an error in a system common to all. It is impossible to say what the actual problem was, especially now that it has gone away!
