Menu goes away automatically

[b6ad1ccf]

In the menu example, the menu appears when I go in the direction of the button but disappears after a few seconds even though my cursor went on the button supposed to show the menu, so I don't even have the time to read all the entries in the menu. Worse, if the menu appears, I move my cursor to the menu to choose an entry, but I didn't decide myself within 2 seconds, and the menu disappears, not caring that my cursor is on the menu, wtf! This is a huge no-go.
