Ok I'm not only new to these boards but I'm new to the whole GFX design. Lately I've been going on Pixel2Life and GoodTutorials for tutorials to help my learning with this program. While reading a tutorial I came across I encountered a problem.

The tutorial is on making box background (background filled with tiny tiny boxes)

The first thing it said was to open a new 3x3 pixel document and then to wip out the pencil tool and using a 1pt Brush, make 3 pixels (Picture Below).



My problem is that when I try to make the pixels on the bottom and the right, They don't show up. I'm only able to fill that 3x3 pixel document with 2x2 pixels.

Any idea why?
