Melodyne questions - zooming and lost scroll bar

A few Melodyne questions - I'm using Essentials 2.1.2.
 
1.  I've lost the horizontal scroll bar at the bottom.  How do I get it back or can I?  I looked all through menus and can't seem to find a way to turn it back on.
 
2. How do zoom back out?  I clicked the magnifying glass tool to zoom in, and tried to Ctrl-click it to zoom back out and didn't work.
