A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Here's a screen shot of what the Notes pane should look like:
Unfortunately, this version stores far fewer preferences than 2011, so while adjusting the Notes pane size for a presentation will get remembered when that file is reopened, there's no way that I can find to set anything different for a default. It's likely you would have to completely uninstall and reinstall to fix this glitch.
For a workaround, you can open PowerPoint>Preferences>View and change the default to Slide View, which doesn't display either the Note or Slides panes.
As a second workaround, if you click on Notes in the status bar, it will toggle the pane between hidden and displayed.
