Removing the little squares at the corners of my object when using the freehand tool

Hello there everybody,

I have CorelDraw 12 and was wondering if there was a way to remove the little squares that are at the corners and the centers of the edges of my object when I am using the freehand tool. I've done it before but it was a long time ago and now I can't remember how. Not a super big deal, just gets in the way some times when I am trying to draw near one of the little squares.

Thanks a bundle.
