Missing button windows

I have just started to learn Blender with the latest dowload. I am using the Blender 3D: Noob to Pro manual to learn. It says I should have five smaller windows associated with the Editing Button. I have only three. I seem to be missing Mesh Tools and Mesh Tools 1. Is there supposed to be five windows in version 2.42a?

Tab into edit mode.

Note that some noob to pro stuff will be different though since much of it was written for 2.37.

Tabbing into Edit mode did the trick. Thanks alot
