I have always loved PowerPoint, until the 2013 version. Every time I get started, for example a slide is in front of me and I want to add a title or customize the frame where the title goes, I click on the outer line and all the choices drop down.
This is where problem starts: When I start to move my cursor to click on one of the choices, they all disappear! Same with several other areas. If a new box with choices or whatever appears after you click on the basic ribbon items, it will come down, but it will disappear before you get there to make your choice.
