[Solved] Slides disappearing from Notes view

When I'm in the "Normal" view the slides are running down the left side of the window, with the slide I'm working on in the middle of the window. I somehow opened "Masterslide" or something like that, and now when I click on the "Notes" tab to go into the notes part of the slide I'm working on, the slides on the left disappear and I have to click "Normal" to put them back. Wasn't like that before. How do I get it so they don't disappear?
