Why doesn't the Math formula toolbar show up?

I heard there might be a problem or maybe I’m missing something. Why isn’t the formula notation toolbar appearing when I start Math?

If you are refering to Elements window, display it by checking View → Elements.

I found it but this time I don’t see the lower side of the window where I should write the formula. Also, typing does not do anything.

@PetruD, Did you figure out how to make the Formula Notation Toolbar work for you?
