Proportional Editing moves whole object I'm trying to follow a video tutorial to learn how to modelling a character in blender. I've reach the point where he explains how to use the Proportional Editing. I'm tryng to do what he says, but this feature is not working in the same way as it works in the tutorial and I don't know why. These are the steps I do :


I activate the Proportional Editing by pressing O
I select a vertex
I press G


What I see is not the movements of a lot of vertex together, but of the whole object. Please check the picture attached where you will see that I've tried to move a vertex with the G and you see what's happened.
That happens a lot, especially if you've set units for your scene. Simply scroll down with your scroll wheel, and the ring will get smaller and smaller, until you see it in your viewport. 

Check to see if the "proportional size" number is decreasing.
