white area in a selected component Altium

[alexrp]

Hi! I'm new using Altium.. I'm trying to make a PCB which can be connected to the chipkit uno32, the problem is when I try to bring near two pin headers, I can't... there is a white area around the components and I can't eliminated it. Here is an image with the problem, thanks!!

I'm not an Altium user, but I did look at its features today and one of them involves showing the clearance around tracks - I wonder if its doing the same for the component?
