Editing/Highlighting Issue

I’m not an editing superuser… I use Audacity to edit out Ums and Ahs from a couple podcasts I do. Everything has worked fine and for the most part still is, but I think I accidentally ctrl something and my editing windows have looked like the attached image ever since. As you can see when I try to highlight audio it ends up being in the background which makes it impossible to be exact in my edits. I’m hoping that someone far more knowledgeable than myself can tell me how to merge the audio and background together again. Thanks in advance.

Audacity 2.0.4
Downloaded form Audacity page as exe

You’ve (probably accidentally) selected the Multi-tool - click on the Selection Tool (the I-beam) - see this page in the manual: http://manual.audacityteam.org/o/man/tools_toolbar.html
