I think the icons got smaller that's why it looks farther.

Click once on the Desktop to make sure it is selected, then Hold CTRL and scroll UP or DOWN with your mouse. This will change the size of the icons along with their positioning (depending on the size, Windows decides how to position them in the grid).

I'm using Blender 2.73 and I'm trying to create tiles using the brick texture node.  The problem I'm having is that the horizontal mortar size is smaller than the vertical.

Is it possible to have them be equivalent sizes?
