Female speaking voice down in pitch

I wanted to give cubase another chance, so I tried again with VariAudio. Apparently Cubase is more capable of varying the pitch of a singing voice than a speaking voice. As you can see on the ScreenShot, parts of the words are not analyzed at all. These remain then in the original pitch. Furthermore, when all events are selected, it is very difficult to move them up or down with the mouse. This can only be done with the arrow keys. Furthermore, the possible zoom range is much too small to get a good overview in the vertical editing.
