How do I get my inspector to re-appear?
If your Inspector is not showing up and you are using more than one monitor, this typically means your Inspector was just pulled out of view.
To get the Inspector back in view go into your computer Settings -> System -> Display and change your settings to only one monitor.
That will bring your Inspector back into view. From there, you can switch back to using two monitors. Just be careful as to where you are pulling your inspector to in the future. And if need be, you can simply repeat these steps.
