The menu in the top bar (i believe it's called global menu or application menu, not sure) opens when I press mouse button on it, but immediately closes when I release it. This makes it hard to use, because I have to keep the mouse button pressed all the time I navigate the menu.
How do I switch the behaviour so the menu stays opened when I click it?
Also, this weird behaviour started some time ago, it wasn't always like that. I don't know what triggered it.
