Grabbing an object

I have recently updated to Blender 2.65. When on the last version I could grab fine but on this version when I grab and object it creates a little circle around it. This is annoying when you want to add a new object, because the object already placed moves as well. I have looked everywhere and can’t find an answer. Please help. It may also help to know I am on a mac.

It also has this circle thing when scaling and rotating.
Thank you in advance.

You have enabled Proportional Editing. Either disable it using the icon in the 3d view header (blue circle) or toggle on/off with shortcut O
