waveforms of imported music have white band in middle

Audacity 2.0.6 on Mac OS X Yosemite 10.10.2

When I import music into Audacity from my iTunes library, the waveform has started showing a thick white band running down the length of the middle of the waveform. I think I clumsily hit some kind of keyboard shortcut without realizing it, because it didn’t do this at first. I can’t find a way to undo it. It’s annoying because when I use the curser to select a portion of the waveform to apply an effect, the shadow of the selection doesn’t show up in the white band & so I have no way of know exactly where in the wave form the effect will begin & end. I’m not very computer savvy, so may need help even understanding the answer. Aside from that, I love Audacity & all you volunteers. Darcy Seezaday

I can’t picture what would cause a thick white band.

Shift-Command-3 to take a picture of your whole desktop or Shift-Command-4 and draw a box around Audacity. Post it here.

My guess is that you have changed from the normal “Selection Tool” to the “Multi-Tool”.

The button with the “I” cursor is the normal “selection tool” (Shortcut F1)
The button with the star is the “multi-tool” (Shortcut F6)
