Why does blender select random faces in edit mode? (Ubuntu) I am following this tutorial to model a basic human male https://www.youtube.com/watch?v=h9l9Eq4eX-I 
every time I try to select a face in edit mode it selects a different face either three faces away or on the other side of my mesh it’s becoming very tiresome and I was wondering if anyone else has had the same problem or if you know how to fix it.
Please help as I enjoy using blender but cant do much more than simple texture editing.

I click the face that has the 3D cursor by it but it selects a different one.
In edit mode, you see the three boxes for either putting select mode into 'vertex', 'edge', or 'face'?  Next to that is a button called 'Limit selection to visible'.
When it is 'selected' or darker, selecting parts of the mesh will no longer select what is behind the cursor on the other side.
