I was surprised to find out that I had been running Lightroom in 32-bit mode and so even though I have a fancy computer with tons of ram and multiple cores, Lightroom was puttering along just like it did on my old 2GB core duo machine, YIKES. How did I know? It seems that Lightroom will actually tell you on the opening credits screen if it is running in 64-bit mode. When you open Lightroom the credits screen shows for a few seconds or you can bring it up manually by clicking, Lightroom>About Lightroom.

Here's another article courtesy of TheLightroomLab.com:

The Crop & Straighten Tool is used for two main functions in Lightroom: Cropping a photo and straightening a photo. How creative!

Throughout this tutorial, I may refer to it interchangeably as the Crop Tool or the Straighten Tool depending on what task we’re using it for.
